NWR-2W Float Type Level Meters

The float type level meter is two-wire transmitter that indicates on a pointer scale the detection obtained by the up and down movement of the float on the surface of the water of dams, reservoirs, and water tanks and converts 4-20mA DC electric signals at the same time.

Feature

  • High reliability for the detection of water level, and has a float-type structure with proven results.
  • Can send out alerts (Alerts are selectable from upper limit, lower limit, upper and lower limit, above the upper limit, below the lower limit)
