Abstract: the experiment device of flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. This experiment device, as shown by the scale, measuring tank, stopwatch, measured flowmeter, a benchmark for pumps, pipes, flow meter and the regulating valve. 1 - The scale; 2 - Tank; 3 - Liquid level meter; 4 - Reservoir; 5 - Water pump; - in June and July Differential pressure gauge; 8 - Orifice meter. 。 More flow meter manufacturers choose model price quote you are welcome to inquire, here is a meter scale experiment device of the article details. This experiment device, as shown by the scale, measuring tank, stopwatch, measured flowmeter, a benchmark for pumps, pipes, flow meter and the regulating valve. 1 - The scale; 2 - Tank; 3 - Liquid level meter; 4 - Reservoir; 5 - Water pump; - in June and July Differential pressure gauge; 8 - Orifice meter. 9 - Turbine flowmeter. 10 - Digital speed meter; 11 - The thermometer. 12 - Loose coupling the experiment materials for water, provided by the sink, for water pump and recycled. This experiment adopts the turbine flowmeter for benchmark flowmeter, calibrated orifice meter are installed on the upstream turbine flow meter, there must be a 30 - 50 d straight pipe, the downstream must be greater than 5 - 8 d straight pipe. The tube diameter d1 = 27 mm, orifice diameter d2 = 18 mm orifice flowmeter, pressure method adopts the flange to take pressure. Orifice meter resistance losses take free hole plate face pressure point 3 - 5 d, free orifice plate under 5 - 8d。 Differential pressure measurement with mercury - Water U tube differential pressure gauge. The turbine flowmeter calibration with gravimetric method. Tank 150 l. Calibration method is: the pump outlet valve control must be opening, maintaining turbine flowmeter flow stabilized, throw loose coupling the water into the tank, the stopwatch and supplement reservoir level at the same time. For measuring tank will full stop, weighing order to calculate flow rate, and the turbine meter reading, work out the flow of flow correction coefficient. Device adopts the pump outlet valve adjusting flow, high exhaust valve, the device for the exhaust pipe. Device and a thermometer to determine each experiment of water temperature. The rotor flowmeter calibration adopts LZB - air 25日,DC - 4 type microphone pump, wet gas flowmeter, a stopwatch, thermometer, pressure differential gauge. This article from: gas flow meter above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
