New Corrosion-resistant, Submersible Level Probe

Apr 21 2008

GE Sensing & Inspection Technologies (Germany) has introduced a new corrosion-resistant, submersible level probe which offers a reliable, accurate and economical solution to level measurement in a wide variety of applications. The new SLP has been developed to allow trouble-free operation in tasks ranging fromlevel measurement in single tanks tomultiple-point level data gathering in high value commodity storage facilities.
The SLP is completely hermetically sealed as a result of its innovative, mechanically robust construction, incorporating corrosion-resistant plastic materials. Consequently, it can be immersed in a wide range of fluids, from hydrocarbons to chemicals and pesticides. It can measure levels up to 70mH2O, to an accuracy of 0.5%, in operating environments ranging from -40°C to +80°C.
The new sensor measures level by measuring hydrostatic pressure, which is a simple, well-established technique. This offers significant advantages over ultrasonic level measurement.
For example, there are no problems with establishing line of sight
between the transmitter and the fluid level, and there is no
possibility that foaming, installation hardware or floating objects
can disrupt readings. Pressure transmitters are not subject to
flood damage and, being submerged, they are protected from vandalism.
Typical applications of the new sensor, which is available in both gauge and absolute versions and requires just a 10VDC, 2mA power supply, include handling a wide range of corrosive fluids in the chemicals and petrochemicals industries, monitoring the levels of silages and chemicals in the agricultural sector and operating in petrol stations and tank farms. It can also be used for environmental monitoring, especially around industrial facilities and sites where there is a potential for pollution, while the fact that it can be connected to data loggers and wireless data systemsmakes it an ideal, economical solution in inventory control and remote data collection.
