Mar 19 2008 Read 1006 Times
economical solution to level measurement in awide variety of applications. The new SLP has been developed to allow trouble-free operation in tasks ranging from level measurement in single tanks to multiple-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 70 m H2o, 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 systems makes it an ideal, economical solution in inventory control and remote data collection.
