The TORBAR is a multiport self-averaging flow meter with a design based on the classical pitot tube concept of fluid flow measurement.

Since the introduction of the TORBAR in 1985, thousands have been installed into a large variety of industries world wide.

Features and Benefits

  • Unique profile shape enables high flow turndown
  • Dual averaging for better accuracy
  • One-piece outer tube for optimum strength
  • Suitable for pipe sizes from 10mm to 8000mm
  • Suitable for square or rectangular section ducts
  • Available as hot-tap for insertion into pressurized pipes
  • Optional direct mounting transmitter arrangement
  • Zero co-efficient drift ensures long term stability
  • Low permanent pressure loss means low energy consumption – and significant cost benefits
  • Low installation costs
  • Long term accuracy
  • Low maintenance costs


General Specifications
