    Some vessels store liquid until it is pumped out. The controller (LIC) acts to start and stop the pump within a specified band. For example, it may start the pump when the level rises to 0.6 m and stop the pump when the level falls to 0.4 m. High and low level alarms (LAH and LAL) warn operating personnel that levels are outside predefined limits.

  9. Encoder receiver transmitter - Wikipedia

    en.wikipedia.org/wiki/Encoder_receiver_transmitter

    Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
