Bronkhorst UK is leader in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
LIQUI-FLOW™ digital Liquid Flow Meters/Controllers for low flow ranges 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.

Full Scale capacities (based on H2O) versus Pressure Rating
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.
Flow control is achieved by integrating a control valve onto the body of the Liquid Flow Meter. This control valve has a purge connection to eliminate air or gas during start-up. The electronic control function forms part of the normal circuitry in the meter.
For ultra low flow ranges, Bronkhorst offers the µ-FLOW series. Ranges: 1,5 ... 30 mg/h up to 0,1 ... 2 g/h IPA- or H2O-equivalent.
