Turbine gas flowmeters

Measurement of a gas rate on a low and high pressure. Turbine flowmeters of SM-RI-X are unique on metrological harakte- to ristika and long-term stability of indications, they are widely used around the world for commercial accounting of gas on transport and the distributor - ny gas pipelines, and also as reference counters on calibration centers. Principle of measurement: The gas flow passing through a flowmeter forces rotate a wheel with blades, the quantity of turns is proportional proshed- to the shy volume of gas. The patented built-in H4H straightening vane effectively eliminates everything asymmetries and flow disturbances. When passing gas through struyevypryami- the tel flow rate of gas raises that increases the impulse transferred on a turbine wheel. It allows to reach the high accuracy of measurements, even on low expenses. The shaft of a wheel of the turbine is installed on reliable bearings. The gear reducer transmits rotation through the magnetic clutch on 8-raz- the line mechanical roller calculating device which is in "head" counter. After passing via the runner gas passes through special the output channel minimizing a pressure loss on the counter. Body of flowmeters is manufactured of GGG-40 cast iron or steel also safety meet the highest standards.
