overview
Is a new type of volumetric flowmeter, also called fonda flowmeter, used for precision of continuous or intermittent measurement of liquid flow in the pipe or instantaneous flow, suitable for heavy oil, polyvinyl alcohol, such as resin viscosity medium flow measurement, small flow can accurate measurement.
Working principle and structure
Flowmeter cavity body has a pair of intermesh gear as the rotor, the two gear and cavity respectively can constitute a fixed volume, known as the standard volume and flow rate is calculated by a certain time to pass through the standard volume to the number of measurement.
characteristics
The flow measurement and fluid flow state matter,
The greater the viscosity of the medium, from gear and measurement in air clearance leakage out of the leakage is small, so the measured medium viscosity, the greater the leakage error the more you small, to measure the more favorable.
Gear meter measuring accuracy is high, suitable for high viscosity medium flow and measuring, but not for containing solid grain fluid, need to add filter. Such as medium mixed gas, can also cause measurement error.
Small volume, light weight, runtime vibration noise is small, can be used to measure the viscosity is as high as 10000 pa s. fluid. Measuring accuracy with a magnitude of 0.5, 0.2 magnitude. Wide measuring range can reach the highest 50:1
A general-purpose, high pressure type, food type and so on many kinds of, applicable to all kinds of cleaning liquid small flow measurement. |
