Specifications

Widely measuring range, lower critical velocity less than 0.5m/s, less pressure loss, strong impact resistance of impeller

turbine flow meter belong to a kind of velocity meter, which featured in high-accuracy, good repeatability, simple mechanism, no moving parts, high pressure resistant, wide measuring range, small in volume, light in weight, less pressure loss, easy-to-maintain and so on.
It is widely used in the measurement of natural gas, coal gas, liquefied gas and light hydrocarbon gas, which has widely use-value in petroleum, chemistry industry, metallurgy and city gas network.

Main features:
1. Widely measuring range, lower critical velocity less than 0.5m/s, less pressure loss, strong impact resistance of impeller.
2. With the high ability of anti-electromagnetic interference and shock resistance, adopting full-sealed self-lubricating bearings Isolation Protection, reliable performance & long working life.
3. The use of advanced ultra-low-power single-chip PC technology, the whole function of strong, low power consumption, superior performance.
4. Accuracy compensation with a non-linear function of intelligent traffic monitor. Correction formula accuracy of better than ± 0.02%.
5. Meter parameters can be corrected on-line with LCD display.
6. Pressure compensation.
