INDUSTRIAL STYLE LIQUID MASS FLOW METERS / CONTROLLERS - LIQUI-FLOW™ series

LIQUI-FLOW™ INDUSTRIAL STYLE LIQUID MASS FLOW METERS / CONTROLLERS

Weatherproof (IP65) and Rugged Design

The LIQUI-FLOW™ series L10I/L20I digital Liquid Flow Meters / Controllers for low flow ranges are equipped with a rugged 'industrial style' (IP65) pc-board housing for use in industrial environments. The instruments operate on a thermal, through-flow measuring principle. The instruments are equipped with a digital pc-board, featuring self-diagnostics, alarm and counter functions, digital communication (RS232) and a variety of fieldbus options.

  • Lowest range 0,25 ... 5 g/h 
  • Highest range 0,02 ... 1 kg/h for fluids with thermal properties similar to H2O

Application story


Liquid Flow Meters / Controllers

Liquid Flow Meters

Liquid mass flow meters of the LIQUI-FLOW™ series are built around a stainless steel tube without any moving parts or obstructions. The heater/sensor assembly is arranged around the tube and, by following the anemometric principle, a constant difference in temperature (ΔT) is created and the energy required to maintain the ΔT is dependent on the mass flow rate. Due to the benefits of the unique patented sensor, the fluid will be warmed to a maximum of 5°C, thereby making the LIQUI-FLOW™ Series suitable for fluids with low boiling points.

Liquid Flow Controllers

The industrial style liquid flow meter can be connected to an industrial style (IP65) control valve to form a closed control loop. The standard direct acting valve (model C2I) is normally closed, has a pressure capability of 100 bar (1500 psi) and a purge connection for easy elimination of air or gas.
