Flow meter RSJ-50 for fuel dispensers, Kyiv

Flow meter RSJ-50 is installed in the hydraulic compartment of the fuel dispenser. And it is intended for measuring the volume of fuel passing through the hydraulic system of the fuel dispensing column. In general, for this piston flowmeter, the accuracy is ±0.2%. Compared to similar products, this accuracy is higher, and its service life is long. The flow meter is an important guarantee of the dosing functionautocisterns. It can still work normally in ultra-low temperatures of minus 40 degrees.

Material and construction of the flowmeter RSJ-50
◈ Body material: aluminum alloy body, stainless steel bushings, composite piston seal, stainless steel rocker mechanism
◈ Structure: stainless steel cylinder liner, four-piston strokes.
◈ Advantage: new appearance, small body, high strength, good wear resistance, accurate measurement, long service life.

Principle of operation
The volume meter is installed in the hydraulic compartment of the fuel dispensing column and is designed to measure the volume of fuel passing through the hydraulic system of the fuel dispensing column. The principle of operation of the volume meter is based on the passage of fuel through the dosing device, inside the housing of which there are four cylinders with pistons working due to the kinetic energy of the liquid passing through them (liquid pressure is created by an externalpump not included in the delivery set). The pistons are placed in pairs on two connecting rods in four mutually perpendicular measuring cylinders with a volume of 0.125 liters each. The fuel enters each of the four cylinders in turn, then it is fed to the output of the volume meter. Pistons with connecting rods under fuel pressure make a reciprocating motion in the cylinders. The connecting rods rotate a vertically located crankshaft, the free end of which protrudes outside the body and is connected to the pulse generator with the help of a coupling. It is supplied complete with a sealing ring ИО50-09 of rectangular section. Sealing rings oil and gasoline resistant with a working temperature range from -40°C to +55°C.
