High viscosity flowmeter

1、 Working principle and structure:

Circular gear flowmeter（High viscosity flowmeter）There is a pair of meshing gears as rotors inside the cavity, and the two gears form a fixed volume with the cavity, called the standard volume. The flow rate is measured by calculating the number of flows passing through the standard volume within a certain period of time.

2、 Characteristics

lFlow measurement is independent of the flow state of the fluid;

lHigh viscosity flowmeterforThe higher the viscosity of the medium, the smaller the amount of leakage from the gap between the gear and the measuring chamber. Therefore, the higher the viscosity of the measured medium, the smaller the leakage error, and the higher the measurement accuracy.

lHigh measurement accuracy, suitable for measuring the flow rate of high viscosity media, but not suitable for fluids containing solid particles, requiring the installation of filters. If gas is mixed in the medium, it can also cause measurement errors.

lSmall size, light weight, low vibration noise during operation, capable of measuring viscosity up to 10000pa.sThe fluid. The measurement accuracy is level 0.5 and level 0.2. The measurement range is wide and the maximum height can reach 50:1

lThere are various forms to choose from, such as universal, high-pressure, food type, etc., suitable for measuring small flow rates of various cleaning liquids.
