Verification fuel dispenser traffic.

A fuel dispensing machine verification requirements must be clearly marked on the tanker and flow measurement transducer measurement range, the flow range with a portable fuel dispenser nameplate is generally (5 ~ 55) L / min, however, due to the run environmental, installation conditions and pipe length, resistance, pressure and other factors, usually reach the upper flow range flow. Through a lot of practice shows that with tanker traffic range roughly (25 ~ 40) L / min. Different flow measuring point, the purpose is to detect refueling tanker metering performance at high flow and low flow. In accordance with the rules of order, the certification process should be separately for each flow point (0.90 ~ 1.0) Qmax and (0.36 ~ 0.44) Qmax measurement, but also on the initial verification (0.14 ~ 0.18) Qmax flow measurement to the point. The largest tanker to tanker traffic site can achieve maximum flowmeter. When gun control measure oil flow, oil injection point in the flow rate gauges should try once filled. This work should have certain skills and proficiency, in addition, understanding test and measurement time staff should also fit, requires repeated practice.
