PURPOSE
Helicoid turbine flow converters ТПРГ are designed to convert the liquid volume flow rate into a frequency electric signal of a sinusoidal form. They are used in processing stations, bench equipment, charging stations of petroleum-refining factories as well as in the diesel oil metering systems.
PRINCIPLE OF OPERATION
The ТПРГ principle of operation is based on the liquid volume flow rate conversion into the angular velocity of the turbine rotation (on the supports in the form of the friction bearings) placed in the stream.
MEASURED MEDIUM
Petroleum and products of its refining, hydraulic system fluids, industrial oils, diesel fuel, hydrocarbon fuels, water.

Qnom – rated flow rate
Pmax – measured liquid maximum operating pressure
Ду - flow section internal diameter
DESIGNATION FOR REQUISITIONING
When ordering it is necessary to specify the converter internal diameter (Ду), type, the measured medium viscosity and pressure.
Example
“Helicoid turbine flow converter ТПРГ20-8-2 ЛГФИ.407221.027ТУ” – a converter with Ду = 20mm with a nipple edge joint for pressure 6.3 МPа connection on friction bearings.
