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.
Sino-Inst specializes in low flow meters for micro to low flow rates. We offer:
Ultrasonic flowmeter can measure low flow rates from 0.1m/s to 5.0m/s.
The gear flowmeter can measure the microflow rate from 0.01 to 0.83.
Coriolis mass flow meters and controllers from 10SCCM~30SLM.
Below, we also introduce a lot of flow meters. based on vortex, electromagnetic, ultrasonic, and positive displacement, etc.
