The range of transmitters is designed for continuous submersion in liquids such as water, oils and fuels
Submersible tank gauging level transmitters from instrumentation specialist Impress Sensors & Systems have been specified for measuring tank fuel levels in remote power generation sites across the world.
For plant operators that need to monitor remote installations such as power generators, vehicles, marine vessels, telecom sites and heavy machinery, the IMTG range of submersible level gauging transmitters from Impress Sensors reliably measures the level of diesel fuel in storage tanks that supply power generators located in remote sites.
The range of transmitters is designed for continuous submersion in liquids such as water, oils and fuels. The transmitters are ideally suited to applications in small (typically 1 or 2m depth) tanks or containers, where conventional mechanical level switches and sensors are not suitable because of reliability issues and a higher degree of level ‘control’ and measurement is required.
The IMTG transmitters use a piezoresistive, silicon pressure sensing technology and a stainless steel diaphragm, which provide excellent stability, repeatability and resolution. The sensor housing is made from stainless steel, making it ideal for reliable, repeatable hydrostatic level measurement. The sensors are available in nominal pressure ranges from 0.5mWG to 10mWG.
Sam Drury from Impress Sensors & Systems comments: “For remote telecom sites that are typically unmanned, network operators need to monitor the fuel levels in real time for fuel consumption rates and for security reasons, i.e. fuel theft detection. For these operators, the IMTG transmitters are submerged in the diesel fuel where they continuously measure the tank level. This data can then be used to generate fuel monitoring reports, which are then used to analyse trends, detect any anomalies and even select a better refuelling date in order to reduce frequency of refuels, which reduces operational costs.”
As well as the standard options, the transmitters can also be custom engineered to suit specific applications. Customers can choose from a range of sensor options, including pressure ranges and engineering units, output types, cable lengths, cable materials, O-ring seal materials, static accuracy and thermal accuracy.
“For diesel fuel storage tank level monitoring, the sensors are supplied with a self-flushing nose cone to provide protection against the sediment in the diesel fuel tanks. The cable material is FEP rather than the standard PVC. The sensors are also calibrated and temperature-compensated for changes in the specific gravity of the diesel when it is subjected to hotter climates,” adds Drury.
The IMTG sensors are supplied with a traceable serial number and calibration certificate. Operating (media) temperatures are from -20°C to +60°C in non-freezing media.
