The SN55A micro gear flow sensor is equipped with double elliptical gears. When the liquid flows into the measuring chamber of the gear flowmeter, the gear drive will be driven. The volume of liquid contained in the space formed by each tooth and the measuring chamber wall is equal. The volume of liquid flowing through can be measured by detecting the number of gears passing through through a specific sensor.
SN55A gear flowmeter is not affected by medium viscosity, and has high measurement accuracy and repeatability, even at the upper and lower limits of the range. It is especially suitable for measuring medium with high viscosity.
