Product Information

HH-LC series oval gear flowmeter is a high accuracy flow instrument used for continuous measurement and features a large measuring range, small pressure loss, strong viscosity adaptability, and others. It is widely used to measure accurately the pipe liquids of oil, chemical, light industry, metallurgy, food, medicine and health, business, and other sectors. Under the action of the liquid pressure difference at the inlet and outlet of the measuring chamber is a pair of oval gears continually rotating on a shaft and eliminating liquid. The rotation cycles of the oval gear can be measured to know the total value of the liquid flowing through the instrument.

Technical Parameters:

1. Maximum allowable error: ≤±0.5% 2. Operating temperature (℃) : -10 ~ +60, +60 ~ +120; 3. Nominal pressure: 1.6 MPa, 2.5 MPa, 2.5 MPa; 4. Pressure loss: 0.1 MPa (when the flow is the smallest as the measured liquid viscosity is within 5-15 MPa•s); 5. Liquid viscosity: 1-300 MPa.s; 6. Accuracy coefficient: class 0.5 and 0.2.
