Wireless Tank Level Monitoring


Thread Starter


Am looking for companies who offer Wireless Tank Level Monitoring solutions/systems in North America. Is wireless tank level monitoring an advantage? What are the advantages? Can i develop it myself? What kind of technology and skills will i require if i have to develop a Wireless Tank Level Monitoring System for my organization?

thank you in advance....

That depends on what kind of level you want to meassure.
Most liquid levels can be measured with a radar level transmitter and than we have ultrasonic sound but that's often more convenient when measuring solids and stuff like that.

But why not check with Emerson Process, Endress & Hausser, Vega, Mobrey or someone of their competators?

The skills and technologies i guess depend on what material, but I can't help you there.

Best Regards & good Luck!
Take a look at these companies. Some of them have 4-20 mA units which you can attach a loop powered level transmitter.

The advantage is cost savings in installation. No, or very little, wiring is needed.

Disadvantage could be: battery maintenance, maintenance fees (see Xsilogy below), not continuous readings.

Developing one yourself? I tip my hat to you. I think with the time you would invest in making sure it is reliable, you'd be better off just using something that has been proven.

We've used Barton and Xsilogy.

Barton's is either radar or ultrasonic (I don't remember), but they send the level signal once every 10 or 15 minutes to a reciever. So, the level is not instantaneous. They also have limits on the height of the tank. The reciever can be tied to a computer, or (I think), tied into a PLC or DCS.

Xsilogy is similar, but I haven't worked with them. I do know they only offer service through them. The tank level signals go to a reciever that is tied to a server class PC. Then it is tied to Xsilogy's server, where the information is displayed on an internet web page that only you can access.

By wireless tank level monitoring, I assume you are talking about a remote telemetry unit. There are many vendors out there that will provide a complete system. One is Microcomm, another is Omnex, along with many others. Yes you can do it yourself, with some gotchas. FCC licensing may be one you need to investigate depending on the method of transmission.

Try searching the internet for the multitude of companies who provide this type of solution.

Off the shelf Milltonics Ultra-sonic probes with a secure web based application which provides data via, wirelss, sat. or land line connection is available right now.

Try doing your own research.
There are several companies devoted to do telemetry using GPRS, with this technology you can do monitoring, control, database.

If you wish we can give you some help.

A simple solution for me is:

you can out a PLC with analog inputs to look the level of the tanks. The PLC must have a LAN interface to connect it with a wireless access point. Then with a simple IP you can monitor the levels from your PC local network... where ever you are...in the world, by internet ;-)

Wireless access points with external antennas can establish communication in a very long distance...
Wireless communication is not directly related with Tank Gauging/Monitoring systems. It is just anoter way to communicate data from the field to the control room, and vice versa... There are many "wireless devices" that you can hook up to your level gauge and send the information to your inventory system.

You may check at http://www.enrafinc.com. They are tank gauging manufacturers and have had experience with wireless projects....

Can't let this one go, Wireless access points are of VERY limited use in a manufacturing environment. I can't get a good quality unit to connect to the next room in a dairy full of stainless steel and cables. also stone walls are a BIG absorber of 2.4 Ghz, My home has 75cm stone walls, one is enough to cut off ALL signal. I would limit the use to line of sight, probably 25m or so for full speed.

Hasn't it struck anyone why such a brilliant idea as wireless networking hasn't taken off in a big way? the protocol is a dog's breakfast and most ms implementations are flaky, great for surfing in the garden though :)

Glen Sprouse - ACSYS Technologies

We do. We are a system integrator firm (part of a larger group of four companies located in the Memphis, TN, Jackson, TN and Atlanta, GA areas). We provide process control and process monitoring solutions for the food and beverage industry (particularly the brewing industry). We have developed several turn-key solutions for wireless monitoring of tank levels throughout facilities using radar, microwave and laser technology. We even provide the front end SCADA and HMI components as well as interfacing to existing SCADA and DCS systems.

Hello ehsan,

I've called the remote tank monitoring market my home since the late 90's. I have since started my own company after being part of various development teams out of Silicon Valley and beyond.

Many would say they have mastered this application. However, I've seen $Billion companies decisively miss targets and then miss them again. In general, there are many more pitfalls than anyone would ever imagine.

To answer your question, the best solution is one that fits your needs. Not having all of your system, application and business requirements all I can say is try to look at the following six parameters and see which developer or application service company can meet your needs:
if questions, email me: [email protected]

1. What is in the tank? Fuel-intrinsinically safe, chemicals-caustic or acid. Essentially this is a question related to sensor/hardware optimization.
2. How is the sensor best integrated? Top-Ultrasonic, Bottom-Differential Presssure, flow meter-in/out, Contact-high/low or overflow. Any multiple tanks/site?
3. LAN or WAN communication? If your tank is proximal to a LAN, can you 802.xx, WiFi, short haul RF, or hardwire?
If remote do you need analog cellular, GPRS/CDMA, Satellite or combination?
4. Power. If local, can you hardwire or battery operate? If remote, can you battery operate or do you need solar charging?
5. Communication frequency? Continuous one way or two way, minutely, hourly, daily, monthly, alarm(usually high or low level) activated.
6. Cost. Yes, there are inexpensive hardware choices, but beware of the burdens created elsewhere like maintenance and installation.
7. Installaion. some applications are self installed, some require 3rd and 4th party installation teams.

In response to your wireless level transmitter. Do you have an transmitter with an analog output that I can wire to my PLC. The tank being monitored is a rather small tank approximately 30 inches deep by 22 inches wide. Please let me know.
Take a look at these Telemetry PLC Modules with GSM/GPRS modems inside, with network possibilities, and a free unique OPC Server that can automatic receive and handle alarms on events from the modules. The OPC server works with minimal traffic to reduce traffic costs. Serial port for communication and mapping of local PLCs. They are very useful when you want to have control over small sites without any geographic limits.

Remote application management introduced an application for managing and reading tank levels, the Global Level management module GLM. This module enables you as customer to measure the contents of large numbers of tanks on location. This actual level will be presented by a matrix and/or graphically via the internet. This information can be used by a purchase department to order new filling on the right moment in time. Also with this information a supplier is able to plan his route at the most efficient way. With this sophisticated hardware and application software, considerable savings could be realised on logistical costs and stocks. Downtime coursed by an empty tank is history and a refill of a tank only occurs when necessary. The system also could be used by maximum levels when a tank is filled. This system measures not only liquid levels but could also be used for other materials like weed, cement, etc.

As expressed before the levels are shown in graphics and matrixes by means of Internet. Graphs by location and a overview in matrix layout of all selected locations. By means of the matrix and the (free) adjustable alarm levels gives a fast view of the desired quantity product by location. See for an example http://www.technologytrading-data.nl

For a complete all in one solution over GSM radio you can use the TBOX LT-200GE. This unit uses the Cellualar GSM network and GPRS wireless internet prototocl. No license required just a GSM SIM card account for around $20 a month. The unit offers a plc, datalogger, alarming system and mini scada and embedded radio modem all in one.
