Experimental setup for flow meter

Abstract: The information of the experimental device of the flow meter is provided by the excellent manufacturers of flow meters and flow meters. The experimental device is shown in the figure below. It consists of a scale, a measuring tank, a stopwatch, a water supply pump, a pipeline, a flowmeter under test, a reference flowmeter and a regulating valve. 1- Weighing scale; 2- Measuring tank; 3- Liquid level gauge; 4- Storage tank; 5- Water pump; 6, 7- Differential pressure gauge; 8- Orifice flow meter; More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the experimental device of the flowmeter. The experimental device is shown in the figure below. It consists of a scale, a measuring tank, a stopwatch, a water supply pump, a pipeline, a flowmeter under test, a reference flowmeter and a regulating valve. 1- Weighing scale; 2- Measuring tank; 3- Liquid level gauge; 4- Storage tank; 5- Water pump; 6, 7- Differential pressure gauge; 8- Orifice flow meter; 9- Turbine flow meter; ; 11 - Thermometer; 12 - Active joint The material in this experiment is water, which is provided by the water tank and the water supply pump and used for recycling. In this experiment, the turbine flowmeter is used as the reference flowmeter. The calibrated orifice plate flowmeter is installed upstream of the turbine flowmeter. There must be a 30-50d straight pipe section, and the downstream must have a straight pipe section greater than 5-8d. The inner diameter of the pipe is d1=27mm, the diameter of the orifice of the orifice flowmeter is d2=18mm, and the pressure taking method adopts the flange pressure taking method. The resistance loss of the orifice flowmeter is 3-5d on the free orifice end face at the pressure point, and 5-8d on the lower free orifice. The differential pressure is measured by a mercury-water U-tube differential pressure gauge. The gravimetric method is used for the calibration of turbine flowmeters. Measuring tank 150L. The calibration method is: control a certain opening of the pump outlet valve, after maintaining the flow rate of the turbine flowmeter stable, pull the flexible joint to make the water flow into the metering tank, and at the same time stop the stopwatch and replenish the liquid level of the storage tank. Stop when the metering tank is full, weigh and order the calculated flow, compare it with the reading of the turbine flowmeter, and calculate the flow correction coefficient under this flow. The device adopts a pump outlet valve to adjust the flow, and a vent valve is set at the height of the device to facilitate pipeline exhaust. The device also has a thermometer to measure the water temperature for each experiment. The calibration of the air rotor flowmeter adopts LZB-25, DC-4 type microphone pump, wet gas flowmeter, stopwatch, thermometer and differential pressure gauge.
