Omni-RRH Flow Transmitter

Description

The OmniPlus-RRH flow transmitter is designed to monitor water and low viscosity liquids. The flow transmitter utilises an impeller and hall-effect sensor to pick up the speed of the flows. It features an easy-to-read backlit graphical LCD display, analogue output (4-20mA or 0-10V), and two programmable switches, operable through a programming ring for settings adjustments. The transmitter’s construction includes a Brass (Nickel-plated), or Stainless Steel, housing and a display with a hardened mineral glass pane and an Aluminium housing, suitable for industrial use and capable of operation and measurement in both forward and reverse flow directions

Features

  • Optimised for use with water and low viscosity liquids
  • Analogue output 4-20mA or 0-10V
  • Two programmable switches
  • Graphical LCD display, backlit, can be read in sunlight and in the dark
  • Selectable units in the display
  • Programmable parameters via rotatable, multi-function ring
  • Electronics housing with non-scratch, chemically resistant glass
  • Rotatable electronic housing for best reading position
  • Designed for industrial use

Applications

  • Flow monitoring in cooling and lubricoolant applications
  • Ideal for higher working pressures, up to 100 Bar, (RRH-025..M: PN 40)

The OmniPlus-RRH Flow Transmitter incorporates programmable switching capabilities, offering two independent switch outputs. These switches can be configured to trigger alarms or control external devices based on predefined flow thresholds. The programming interface includes a graphical display and multi-function programming ring, which allows users to set parameters such as switching points and hysteresis.
