Omni-VHS Flow Transmitter/Switch

Description

The Omni-VHS flow transmitter is designed to monitor viscous media like oil, utilising a volumetric principle with two interlacing screws driven by the flowing medium to achieve measurements largely independent of viscosity. 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 and protection against unintended changes. The transmitter’s construction includes a stainless steel case with a hardened mineral glass pane and an aluminum housing, suitable for industrial use and capable of operation and measurement in both forward and reverse flow directions

Features

  • Measures and monitors viscous media (oil) 1.4 up to 2500 l/min
  • Connection 1″ up to 2½” BSP
  • Very low dependence on viscosity
  • Can be used up to 40,000 mm²/s (cSt)
  • Light and compact device (aluminium housing)
  • Operation and measurement possible with forwards and reverse flow
  • For cost-sensitive applications
  • 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, removable ring (programming protection)
  • Electronics housing with non-scratch, chemically resistant glass
  • Rotatable electronic housing for best reading position
  • Designed for industrial use
  • Small, compact construction
  • Simple installation
