LIQUI-FLOW Series L10/L20 Flow Meter/Controller

Brand: Bronkhorst

Bronkhorst has been the pioneer in the field of micro to low flow liquid metering instruments based on a thermal measuring principle.

The digital LIQUI-FLOW Mass Flow Meter was designed to cover the range between 5 to 1,000 g/h Full Scale in a compact instrument with a fast response.

The Flow Meter is basically a stainless steel tube without any moving parts or built-in 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 of the mass flow rate.

Due to the benefits of the unique patented sensor, the fluid will be warmed to a maximum of 5° C (41° F), thereby making the L10/L20 series suitable for fluids with low boiling points.
