This ex-proof pulse generator FBCGQ-3 is an electro-mechanical device intended to convert mechanical rotation of its pin in the sequence of rectangular pulses. It is used for operation as a part of the fuel dispenser. The pulse generator structurally consists of a body and a cover of cylindrical shape connected by four screws. The body material is aluminum alloy, assuring the protection degree against external impact IP 44. The support bracket, made of aluminum alloy by means of which the generator is fastened to the fuel volume meter of fuel dispenser, is connected to the body by screws. The pivot pin made of stainless steel, whereon a thin metal disc is fastened is set into the generator body. 100 small rectangular slots are performed in the disc along the circle at the same distance. The disc plane is located between the receiving and transmitting parts of the opto electronic couple. Operating conditions of the pulse generator: temperature of -40℃ to plus 50℃, air humidity from 30% to 100% at 25℃. Working principle of Pulse Generator The rotation of the volume meter shaft is transferred to the generator pin by means of the reducing bushing in the fuel dispenser. The disc with slots fastened on the pin rotates in the gap of the optoelectric couple, as a result it forms an output pulse signal. The quantity of the formed electrical pulses is proportional to the revolution angle and the quantity of revolutions of the volume meter shaft and as a result to the fuel volume which passed through the volume meter. For one full revolution of the pin the generator forms 100 pulses for each output. Counting the quantity of these pulses by means of external measuring indicator enables to determine the value of the revolution angle and the quantity of revolutions of the generator determines the quantity of fuel, which passed through the fuel dispenser volume meter that enables to control the process of dozing and selling of the fuel to the consumer. The generator pin can rotate both clockwise and anti-clockwise. When rotating the pin clockwise (if to look at the generator cover from above), the signal of the second channel is slow relative to the first channel signal. Using this effect the measuring indicator can determine and control the direction of the generator pin rotation. Technical Parameters Model FBCGQ-3 Supply voltage 5-12v Consumption current, no more 20mA Quantity of output circuits 2 Output sink current in the circuit “CH1”, “CH2”, no more 50mA Phase shift between output signals 40-130 degrees Quantity of pulses for each output per one revolution of the pin 100 Weight 0.7kg

The flow meter RSJ-50 is installed in the hydraulic compartment of the fuel dispenser. And it is designed to measure the volume of fuel passing through the hydraulic system of the fuel dispenser. In general, for this piston flowmeter, its accuracy is ±0.2%. Compared with similar products, this accuracy is higher and its lifespan is long-lasting. The flowmeter is an important guarantee for the metering function of the tanker. It can still work normally in an ultra-low temperature environment of minus 40 degrees. Material & Structure of Flow Meter RSJ-50 ◈Body material: aluminum alloy housing, stainless steel sleeves, composite piston seal, stainless steel rocker mechanism◈Structure: stainless steel cylinder liner, four-piston strokes◈Advantage: novel appearance, small body, high strength, good wear resistance, accurate measurement, long service life. Working principle The principle of operation of flow meter RSJ-50 is based on the passage of fuel through a metering device. Inside the flowmeter housing, it has four cylinders with pistons operating due to the kinetic energy of the liquid passing through them. The pressure of the liquid is created by an external oil transfer pump – ZYB-50. The pistons are placed in pairs on two connecting rods in four mutually perpendicular measuring cylinders with a volume of 0.125 liters each. Fuel alternately enters each of the four cylinders, then is fed to the output of the volume meter. Pistons with connecting rods under the pressure of fuel perform reciprocating motion in the cylinders. Connecting rods rotate a vertically positioned crankshaft, the free end of which protrudes outside the housing and is connected to the pulse generator by means of a coupling. It can complete with a rectangular O-ring IO50-09. Besides, O-rings are oil & gas-resistant with an operating temperature range from -40°C to +55°C.

We offers high quality hose for oil & gas recovery. Gas station oil and gas recovery refers to the collection of volatilized gasoline oil and gas during the process of loading and unloading gasoline and refueling vehicles, or reducing the pollution of oil and gas by one or two methods of absorption, adsorption or condensation, or change the oil and gas from gaseous to liquid, and then to gasoline again, so as to achieve the purpose of recycling. The oil and gas recovery coaxial hose is used in the oil and gas recovery system of the oil dispenser. During the refueling process, it is connected to the oil and gas recovery fuel nozzle and the oil and gas separation valve. Between the middle layer and the outer wall is an oil circuit, and the middle pipe is a gas circuit. When refueling, the oil and gas are drawn into the underground oil tank from the gas circuit. The metal braid of the tube provides excellent kink resistance, low elongation and long service life.
