Model 22VMU Flow Measurement and Flow Control System

Model 22VMU Flow Measurement and Flow Control System

The 22VMU is a self-contained, electronic flow measuring and flow control system. Based upon the variables of valve differential pressure and valve position, the ValveMeter Ultra automatically calculates, displays and controls the flow to the control set point. With the ValveMeter Ultra, there is no need for a separate flow meter in the line. Typical examples include water transmission lines, water treatment plants and pump stations.

  • Complete package, no additional hardware required
  • Sizes 4″-24″
  • Wider range of flow control than standard hydraulic systems
  • User-friendly color touch screen operation
  • Full function PID controller
  • User-selectable flow units (USGPM, m3/hr, L/S, MGD)
  • Allows for frequent set point change
  • Local (touch screen) or remote (4-20 mA or digital) set point selection
  • Valve scheduling for control parameter modification (Time, Day of Week, Process variables)
  • 4-20 mA output of metered flow rate
  • Includes totalizer (sums the total number of gallons that have flown through the valve since the totalizer reset. Measured in USGPM, m3/hr, L/S or MGD)
  • RS232/RS485 communications (CANBUS, MODBUS)
  • 100-260Vac 50-60Hz with 24/12 VDC, or solar Powered units available
  • Optional:
