Low Flow Meters

What is a low flow meter?

Low Flow Meters refer to those flow meters that can be used to measure micro-flow-low-flow rate media. Including metal rotor type, gear type, electromagnetic type microflow meter, microturbine type, and thermal type small mass flow meter. It can measure the Low flow rate of a variety of liquids and gases. For example, it needs small volume, high-temperature resistance, low-temperature resistance, or medium viscosity. etc. We all have suitable product recommendations.
