The Best Propane Tank Monitor For You Depends on These Specific Factors

By Andrew Erickson

March 5, 2023


The best propane tank monitor isn't a single product for everyone. The correct answer to that question is going to vary based on your individual situation and circumstances.

That's why I'm going to describe for you several scenarios so you can determine which one most closely resembles you.

For backup generators at remote telecom sites and commercial buildings, choose a professional-grade tank monitor

This is where my experience on this topic comes, as DPS monitoring devices are frequently used for propane/diesel tank monitoring at remote telecom huts. This is usually part of a broader monitoring device that simultaneously monitors the generator status and other equipment alarms.

Let's take a look at the core components of a typical professional-grade system that will monitor your propane tank:

  • A sensor to monitor your tank (either an external magnetic sensor attached to the needle gauge or an integrated sensor from your generator).
  • A remote monitoring device (ex. RTU) that can receive data from the sensor (or talk to your generator with a protocol like Modbus).
  • A method of getting low-fuel alerts back to you (either a central alarm management server or a simple notification like email or SMS text).

In a DPS context, we frequently implement a solution that includes these specific devices:

  • The most common propane sensor that I deploy in my projects is the Rochester "Remote Ready (R3D) Dial & Hall Effect Module for LP Applications". I have to supply it with 5 VDC. The other 2 wires provide a variable voltage of 0-5 VDC to reflect the level of the propane tank.
  • I pick up the 0-5 volts from the propane sensor using a NetGuardian RTU (various sizes exist and are selected based on the other monitoring goals at the remote site).
  • When more than 10 sites are involved, I'll typically recommend a T/Mon master station to collect alarm data from each of the 10+ NetGuardians. With a smaller network, it's usually fine to just manage the NetGuardians independently using their web interfaces and have them send email alerts (or email-to-SMS via a wireless provider's gateway email address system).

Hard-to-reach remote sites can be easily monitored with NetGuardian RTUs. This includes propane/diesel fuel tanks, the generator itself, and miscellaneous telecom and other equipment in operation at the site.

These solutions can vary in price from less than $1000 for the smallest possible RTU to much more if many large sites are involved.

In any case, quality is much more important than price reduction in a serious telecom context. You're providing important service for your employees and/or the public. Your uptime directly impacts 911 service, the power grid, police, fire departments, EMS, etc.

When you're shopping for propane monitoring equipment, ask your vendors whether they've done this kind of thing before. Who manufactures their hardware? Who writes their software?

Finally, choose a company that can provide you with good technical support. A lot of the time, when there's an issue with propane tank monitoring systems, it's because of incorrect installation - not the actual hardware or software. Nobody benefits if your propane tank runs dry, so make sure you're working with people who know what they're doing and will give you tech support without charging a fortune.

If you need it, turn-key installation service is also a way to make sure everything is set up correctly. You don't want a mountaintop site that's snowed in for the winter to run low on propane.

For home users, $200 systems with WiFi and a cloud-based smartphone app are popular

Oddly enough, I also get a lot of inbound calls from homeowners who have watched my general overview video of propane tank sensor technology. This wasn't my intention when I published that video for my clients at DPS, but tank floats work the same no matter the scale of your operation or home.

After a few calls, I located a monitoring system from a company called TankUtility. I tend to see it retailing for $200, and it's where I've been directing consumers who call me to ask about the best propane monitoring system for them. For most of these consumer applications, a $1000+ system is a non-starter.

If you're looking to monitor a propane tank at your home or business, then you don't need the same level of monitoring as commercial sites. A simpler and more affordable solution is to get a wireless tank monitor. These integrate seamlessly with your home's wireless internet and generally run on a built-in battery.

From a selfish perspective, I also don't have to worry about any loss to my core business. WiFi is not often available and frequently undesirable at telecom equipment sites where security is a concern.

For RV owners, seek guidance from your RV maker or commercially available third-party devices

One group that I haven't really been able to help much has been the RV owners who have called me after watching my propane-sensor video. Probably about 25% of my inbound calls from consumers have been from people with RVs.

I have been able to explain my experience in propane monitoring and offer guidance to those with advanced electronic skill (ex. "0-5 VDC is the output you can expect from many sensors"), but I have not found anything easily available after a bit of searching.

That's why, if you've landed here and have an RV, I recommend that you contact your RV maker for a solution. Most of the people who contact me have an existing gauge that is broken, so the original vehicle manufacturer must have some kind of option for you.

There also are likely some options available from third-party manufacturers. My search has not been exhaustive, so you may well find something.

Give me a call for a recommendation of the best propane monitor for you

It's impossible for me to write an article that covers 100% of the criteria you need to think about to select the best possible propane monitoring device for your specific situation. If you still have questions or uncertainty, your best next step is to just give me a call.

I'll talk to you about what you know so far and ask you some questions to fill in the holes in your plan. After learning about your situation, I'll be able to recommend a system that will provide excellent monitoring of your propane tank for years to come.
