5.About flow meter MOQ
The minimum order quantity (MOQ) for a flow meter will depend on the type of flow meter and the manufacturer. Generally, the MOQ for a flow meter is between 1 and 10 units, but it can vary depending on the manufacturer and the type of flow meter.
6.How does a flow meter measure flow?
A flow meter measures flow by measuring the velocity of a fluid as it passes through a pipe or other conduit. This is typically done by measuring the pressure drop across a known area, or by measuring the time it takes for a volume of fluid to pass through a known area. Other methods include using a turbine, paddle wheel, or ultrasonic transducer to measure the velocity of the fluid.
7.How does the flow meter detect the properties of the target fluid?
Flow meters measure the flow rate of a fluid by detecting the velocity of the fluid. This is typically done by measuring the pressure drop across a known restriction in the flow path, or by measuring the velocity of the fluid using a variety of technologies such as ultrasonic, magnetic, or thermal. The flow rate can then be used to calculate the properties of the fluid, such as density, viscosity, and volumetric flow rate.
