I have 2 275 gal above basis dwelling house heating oil tanks. My problem is that my boiler is using oil from merely one of the tanks how exercise I fix the problem

Jimmy Sers said:

I just came beyond this smart oil gauge (TM) that has a app that gives you readings to your telephone through their custom app!! No more than float gauges for me I'm buying ane likewise I'm curious to know when the oil company fills my tanks how accurate they are in counting gallons and charging me

Moderator adds:

The Smart Oil Gauge™ measures the level in your tank throughout the day and transmits this data over your home's Wi-Fi network.

When a tank gauge shows empty how much oil is left in the tank, like when a auto is on empty. In that location'south commonly a couple gallon however in it

The estimate is not a precise instrument. Measuring from the summit, center, or bottom of the disc are all fine. Consider that for a typical oval shaped oil tank, the gauge is only close to accurate when the tank is total, half empty, and fully empty. As I worry most running out of oil and losing oestrus and having freezing pipes and water impairment in buildings, I take the more conservative arroyo and call the oil company if the bottom of the approximate is in the one/four range or lower.

thanks I am checking my sons house and the estimate looks to be five/16 thick. Didn't know if I should read bottom, middle or top of disc. Emptied h2o which was chocolate dark-brown. Restarted burner. burner works just there'southward a weird sound (much like a screech). Figure tank is MT. Thank you for info

Jamie,

First let'southward check for a stuck oil tank gauge - some gauges accept a removable plastic embrace that lets you press the level indicator down or pull it gently upwardly to assure it's not jammed. Of grade the fourth dimension to check the gauge would be correct later on the tank has been filled.

Mayhap yous oil company is adulterous you lot. If they deliver the oil warm information technology seems full on the gauge but will drop the level when it cools. A lot of oil company's don't provide the correct oil they say they give. One mode for the oil company to offer inexpensive pricing. They but don't give you all the oil.

Question: replacement oil tank gauge parts

The plastic cover that covers (shows the one/8 markings) the estimate of my oil tank broke/cracked.
Do you know where I can get a replacement? - Robert Muller

I take got a Worcester Camray 5 which is located in the garden. I had an indoor plug in oil level indicator just it has gone missing - where can I get a replacement one please. - Karen Gallant half dozen/27/12

Reply:

The plastic part that covers your oil tank gauge is chosen the guess vial. You can get one from a local oil heating equipment parts supplier or online. At oil storage tank gauge vials [above in this commodity] we have added photos and details. - Reader G.C. [Thanks GC] .

Karen the Worcester Camray 5 is a discontinued oil fired heating boiler. I don't know almost the oil level indicator you cite - but if it is a device mounted on your oil piping or oil tank, I would imagine your oil heat service visitor can install a generic replacement.

Question: oil tank gauge not working

Question on a fuel oil tank estimate: 275 gallon outside, vertical, 8 years old, in skillful repair. Sees Maryland winters.
Terminal spring, my oil supplier left a note that the standard float estimate did non work. In summertime, I removed and cleaned the plastic dial cover with Mineral Spirits and a bottle brush

It was heavily coated inside, almost opaque, a brilliant red hardened gum. And so gently pushed the bladder down into a full tank, cycled this slowly several times total range, and it worked for almost a season. Now with the last fill upwards, information technology again is stuck on empty. Is in that location a gum in No 2 FO? Does it splash up and glue the float machinery? How frequently does the guess need maintenance? Mr. R.Fifty. Hails Sr. P.Due east. 2/25/2012

Reply:

Oil tank gauges often piece of work reliably for decades and practice not require maintenance. On occasion if a gauge stops working it's possible to gratis upward stuck parts by simply moving the judge operating parts a bit. If that doesn't piece of work, replace the approximate.

Question: oil tank approximate does not return to full position even though tank is full

I have a float gage (319 gallon indoor oval tank), the tank went empty and was filled with 200 gallons however the gage did not render to testify approximately 3/4 total. Is it because there is liquid sitting on top of the bladder gage? If and so, is in that location a fashion to right this so the tank reads accurately? - Ian eight/7/12

Answer:

Ian,

The float arm may be bent or the gauge sticking. Y'all should exist able to carefully detach, remove from tank, un-bend, united nations-stick moving parts (or replace them).

If your oil tank approximate looks like the ane at the top of this page, try first unscrewing the plastic cover and press down gently on the judge top indicator - the whole associates volition move and you're pushing the tank float and arm up and downwards inside the tank - sometimes this will gratis up the assembly without further ado.

Question: what is an oil tank whistle and how does it chronicle to oil deliveries?

Oil won't exist delivered unless the tank gives out a whistle, delight explain since I'm new at this. and what tin can I do. Thanks. - Felix S 11/12/12

Reply:

Felix,

The oil tank whistle is a device at the meridian of the oil tank that emits a audio that lets the oil delivery truck driver know when the tank is full. Information technology has nothing to do with the transfer of oil from the oil tank to the heating oil burner.

I have been working on it for 4 hours a day at 60 degrees. I turn it downwards to 50 degrees when I leave. In one week I checked the cuff and it was at 3/8s of a tank.

Question: how to supplant an oil tank guage where space is express

(Feb 26, 2013) Robin A said:

I take a 275 G tank without a TLI. The ane.v" vent line has a capped terminate that I stick a stick in to come across what the level of oil is. The top of the capped nipple is almost 10" in a higher place the height of the tank. Can I simply stick a TLI in this hole? I have found a couple examples that I think will work such equally the Krueger Sentry Galvanized Direct Reading Gauge. Information technology indicates information technology has a "tank depth" of 6" and I'm non sure what that means. I too plant a similar estimate that has a "tank depth" of ten" - non sure what that means either. Tin can you help? Thank you!

Reply:

Robin A

Most likely the oil tank fuel level gauges yous describe, when they refer to a "tank depth of 10" " are saying that the approximate can measure oil level in a tank at depths anywhere *between* 10" and a deeper level, typicalliy 144".

You demand room above the tank to insert the new gauge and you'll be all prepare.

There are diverse LED and other electronic oil tank fuel level gauges that let remote reading of the level of oil in the tank, but all of them require some sort of sensor or bladder inside the tank where the oil level will be monitored.

Krueger, the company you mentioned, provides an "LED at a Glance" LED Clench-on device that will convert the position of the bladder gauge indicator into an electronic point of oil level that can then exist read by a remote brandish - that feature may non be ane you need.

Question: missing oil tank approximate vial

(Sept nine, 2014) Rob R said:

the guess vial on my tank is broken/missing. The sending unit is working perfectly so I am able to guestimate the gallons of fuel in my tank. I take searched for a replacement vial online merely they all are threaded vials. Mu result is that my gauge is held onto my tank with 4 pocket-sized screws. Yous have a photo of the type that I have as the first picture under your " How do we know that the oil tank gauge is working?" paragraph. There are no threads on the gauge mounting hole. Tin you provide whatsoever insight on how to supercede this type of estimate or vial?

Rob:

It may be nearly unproblematic to replace the unabridged oil tank gauge associates rather than waste material a lot of time looking for an obsolete function. Krueger, mentioned below sells a diverseness of oil tank float gauges and tank bushings that will probably work fine for you lot.

Or use our email found at our CONTACT link and send me some sharp photos of your gauge and I'll see what I can discover for it.

Question: leaky oil storage tank gauge

J. Ross Keys said:

If a supplier overfills a oil tank in the basement of a dwelling and the fill piping is full, is information technology possible that the hydraulic head of the liquid to a higher place the approximate would leak oil? In other words if a plastic level judge is installed correctly, what force per unit area rating are they designed to hold under manufacturing testing?

Reply:

J Ross

Definitely. Oil tank gauges, depending on the type and pattern, tin can leak if an oil storage tank is overfilled. I think that the leakage will be more astringent during fill up-up as the tank is existence filled under pressure, applying greater oil pressure to the gauge and its seals than just that from the head of oil remaining in a fill pipe afterwards. Examples are in the article in a higher place.

What kind of valve to use to prevent air bubbles in the fuel line

(November 26, 2014) Anonymous said:
we accept 2 275 gallon oil tanks. the furnace was not coming on, technician blew out the line, and later a while, some oil came in.

However, he said that the crossover line between the ii tanks must be getting clogged, every bit the oil is not flowing freely from one tank to the other. He measured the forepart one, said information technology had 18 inches, the dorsum ane seems to exist full or close to full. The way the tanks were installed information technology is almost incommunicable to reach the valves on the bottom of the back tank, the crossover line etc. He says they need to empty the tank, and turn them to both face front, and so that a person could get to all the valves etc. Is this really the only way to get?

Answer:

Good grief what a lot of trouble, and what a thoughtless original installation. Unfortunately when blowing out an oil line cannot adequately articulate it, replacing the line is a typical solution, along with apply of an oil additive to break up sludge, forth with sludge removal from the tanks along with increased filtration at the oil burner to avoid clogging by the sludge released past the whole process.

It's just about impossible to install a new balancing line betwixt the 2 tanks connected to tank bottoms without start emptying the tanks. If going to that much trouble (elimination tanks) I'd look at sludge removal at the same time, or even tank replacement if the tanks are quite old and rusted thin since much of the cost is in the labor.

An alternative MIGHT be to close off the clogged lines and install new, larger bore oil lines coming off of the tank tops. But some clever pipage may be needed to assure that both oil tanks are used when tapped from the meridian

(Jan three, 2015) Bearding said:
1 solution that worked for me is to install an oil filter housing without filter in line before your oil filter. This is the everyman point and will gather all the sludge and water. This way the sludge comes to you. The but cost is the housing and a gasket. Techs refer to this method every bit a sludge pot. Promise this helps.

Question: cream formation during heating oil delivery

(Feb 13, 2015) Anonymous said:
I asked the oil human to fill my tank that read i/eight tank. When he came he pumped 110 gal and information technology indicated full to delivery homo. The guage read 1/2. They told me that cream formed when new oil was put into tank that caused it to indicate total and stop pumping. I've never heard of such a matter! Whatsoever comment?

Reply:

Anon:

What you describe is not something I've come up beyond just it has been described as an issue that can occur if there is water contamination in the oil storage tank; during delivery the incoming oil, delivered fast and under pressure, can stir upwards water and form foam - this can besides clog up the heating oil piping, filter, burner, and atomic number 82 to loss of heat.

I'd ask the oil visitor to check oil tank water level, remove excess water, and go from at that place.

I'd besides check - if you lot can - about just what was being delivered to yous - if your oil tank didn't have much h2o in information technology before and then h2o could have come in a bad delivery. I've seen this happen if the oil truck is filled from a depot tank that is low on oil, has water in that tank bottom (which is normal) and is itself stirred by a depot delivery while the oil truck is filling.
