1.0 Introduction
A digitally controlled filling station pump meter is a measuring instrument that record and is proven to be a convenient and accurate tool to calibrate pump meter flow rates, simplifying the calibration and validation procedures pump flow rates from 25ml/min. down to as low as 0.05ml/min. can be measured with an accuracy of ± 1% (one percent) of the flow rate. This type of toll or instrument saves time and labor compared with manually controlled filling station pump meter.
Digitally controlled filling station pump meter were first used in the 1980's, when Chinese scientists discovered the application in a new technology digitally controlled filing station pump meter. It was manual pump meter that gives birth to digitally controlled filling station pump meter technology, as early workers quickly found that the digitally controlled filling station pump meter gave the most accurate result.
In addition, the data or information collected is independent of operator technique and is therefore both more accurate and more precise. Enhance stock reconciliation and identify losses controlling devices and equipments digitally is the latest technology in most engineering field today.
Digitally controlled filling station pump meter is durable and variable-speed digital pump is ideal for bulk fluid transfer and dispensing applications, it can handle large batches quickly and efficiently. Keypad lock/unlock feature helps lock in your settings and prevents accidental or unauthorized changes, it has an improved rotor and occlusion bed design allow easier tube loading and prevent tubing roll during operation, reversible motor has a purge before or after pumping fluid in either direction. Some external dimensions improved accuracy, flow indicating marker, flow ranges and body, built 25% grater wall thickness.
Unexpected pump failure can be costly and time conserving. Hedland says by installing one of it's direct reading flow meter on the pump. Case drain, the user can monitor changes in efficiency by keeping tabs on any increase in case drain flow. The excess case drain flow shows the pump is beginning to fail. This allows you to schedule preventive maintenance and reduces unexpected down time. Hedland's variable area meter has a low pressure drop, typically 1-5ps/G with an accuracy of 2% of full scale. The meter can be installed in any position with no special piping or flow strengtheners.
There is an improvements in the pump meter parts like fuel pump, fuel flow meter, fuel nozzle oil pipe, shut off pull valves, fuel motherboard, fuel display board, fuel power board, fuel keyboard, explosion – proof motor, thermal printer, mechanical counter, IC card socket, solenoid value and pulse sensor.
Finally, digital control pump meter introduce method into one or more vessels such that upper and lower temperature material limits are not exceeded and preferably such vessel are not over or under filled by controlling the filling temperature of the digital controlled filling station pump meter.
