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

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.

Note:
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.
