The automatic, electronic liquid level controller is used for automation of the pump set operation. This is suitable for conductive and non-conductive liquids. However the choice of level sensing probes put the limitation.
501D Series Automat differential pressure transmitter is the part of Series 501, consisting of certified electronics. 501D Series Smart DP transmitters are microprocessor-based instruments that combine the analog signal advantages with (4-20 mA) together with the flexibility of digital communication using HART protocol.
Electronet Equipments, the renowned technology leader in the field of process control instruments for various process parameters like temperature, flow, pressure, level, conductivity and pH, etc., offers a range of instruments specially manufactured for the process industries.
Water/liquid level controllers, LLC-11 and LLC-22, are the most suitable instruments for water/liquid tank level control. The level probe senses the upper/lower level, and operates the relay to energise the motor pump.
