Reliability and accuracy of measuring instruments

Metering tank is still large reserves of liquid in the tank measuring products known. It can be used to measure the stock, namely the determination of the total amount of product in the tank level gauge system can also be used to turn the output measure, that is, as product marketing and tax basis. The main two methods: measurement based on volume and quality. Tank gauging system based on volume, the stock of measurement achieved by measuring the liquid level and temperature. In the tank gauging system based tank level controller on quality, the stock is measured using a liquid measuring hydrostatic liquid column made​​. In turn inventory control measurement or lose, no matter what method, the reliability and accuracy of measuring instruments is very important.

Automatic tank gauge refers to test equipment

Automatic tank level gauge usually refers to the testing of oil lost equipment, which "can be from conventional fuel card management system storage tanks.To detect any part of 0.2 gallons / hour leak rate. "Applies to the narrow definition of this tank level gauge console installed in the tank as well as to read the oil level measurement probe and temperature readings, but now been developed into various forms covering gas station management software environmental monitoring stations - including groundwater monitoring, double-wall "tank sandwich" monitoring, pressure pipeline leak detection and monitoring of tanker chassis can also provide measurements for use in daily inventory inventory control information requirements monthly mechanical fuel level gauge inventory control can detect traffic throughput plus gallons of 1% of the sum of the leak, and made clear that the oil level should be able to measure to the nearest eighth inch at the bottom of the tank.

Oil metering tank

Oil metering tank, not only is the measurement of liquid level, and is a comprehensive system to measure the complex parameters. By comparing  fuel card management system the three main oil tank metering scheme, and analyzed the factors influencing the oil inventory management and metering fuel monitoring system accuracy, reasons and correction of errors is discussed. Can be used as a relatively perfect automatic tank gauging systems for hybrid measurement system level and quality measurement technology based on.

petrol dispenser pump is a direct use of diesel engine driven

petrol dispenser pump is a direct use of diesel engine driven, able to initiate and realize electromechanical equipment of water supply in short time. diesel pump manufacturers is a micro electronic technology, digital technology, computer technology, information processing technology of high-tech products, industrial automation control technology, communication technology and mechanical technology as a whole. Use diesel water pump is very wide, can be used in the following occasions: Industry -- boiler feed water system, cooling water circulation system, the system of smelting -- cooling circulation system fire -- fire hydrant system, sprinkler system, spray cooling system, foam system, water cannon system military -- field water supply system, water collection system heating -- Island water circulation system, cooling system of municipal -- emergency drainage, emergency water agriculture -- system of irrigation and drainage. Adjust the correction fuel injection pump, adjust the oil injection timing and the amount of oil, similar to gasoline engine carburetor and ignition timing correction, helps to increase the engine power, fuel economy, prevent diesel knock.

 

fuel dispenser selection

Tanker selection: 1. should be used with the self-styled refueling gun tanker; 2. gasoline refueling gun gasoline flow rate should not exceed 50L / min. The flow rate should not exceed 4.5m / s; imported vacuum degree 3. auto fuel dispenser self-priming should not be less than 54KPa, the outlet pressure should be less than 0.3MPa; 4. with a gas station should use the same brand of tankers, need retail fuel dispensers installation process tanker refueling vapor recovery systems, oil and gas recovery function should be used with multi-gun 5. multi oil refueling process, you should use a tank to install one or two sets of submersible pumps for multi-gun refueling machine; 6. supply city gas station less than four per tank gun, should use self-priming frequency tanker, when a tank supply more than four guns, should use submersible pump inverter tanker;

fuel dispenser Classification

Tanker Category Description:
Under normal circumstances the user requirements for the tanker to its structure and function are different:
Press count indicates the operating structure can be divided into retail fuel dispensers and electronic fuel dispenser into two categories, with the inherent defects due to a mechanical counting operation, so mechanical tanker has quickly replaced by electronic tankers, especially in the commercial tanker even more so.
If you press the size of the oil transport capacity can be divided into general transportation capacity (the amount of oil is 40 ~ 60L per minute) of the tanker and the large flow (the amount of oil is 80 ~ 90L per minute) tankers.
If you press the number contained in each refueling tanker refueling gun unit or can be divided into single gun tanker, guns and more guns refueling tankers.

Tanker accuracy tolerance

1.tank automation systemgas separation is not good, causing the fuel oil gun solution containing gas, oil and gas separator should check whether the failure of the valve, the exhaust pipe is blocked;
Causing increased leakage within 2 meter accuracy tolerance, you should replace or repair the meter;
3.Sensor inside the double photovoltaic panels (light tank) damage caused by the loss of counting pulses;
4. tanker computer motherboard damage is one of the causes of the gas station management software precision allowed;
5. pipeline leak, when the amount of gas entering the pipeline oil separator for separating gas exceeds the maximum amount of time will cause oil containing gas tanker fault performance for accuracy at this time allowed, the exhaust pipe exhaust more than
