Line flow instrumental calibration training device

Line flow instrumental calibration tr--ning device,Cummins diesel engine running tr--ning platform

1. Project overview

Traffic is an important parameter in production and scientific experiments. Both industrial production and scientific tests require traffic measurement to measure the process or the proportion of the production capacity of the equipment and the proportion of various parts of the flow in order to evaluate the process or equipment. At present, the measuring instrument that measures traffic can be roughly divided into three categories, namely the speed method, volume method and quality flow method.

Although various flow instruments have been calibrated before leaving the factory, and the flow scale marks are established, the operating conditions such as working medium, pressure, and temperature are often different from the original timing during the laboratory or production. In order to accurately use the traffic meter, on -site calibration is needed before use.

This test table m--nly uses a weighing method, calibration and verification of pore board flowmeters, electromagnetic flowmeters, turbine flowmeters, and vortex flowmeters. Use high -precision collection instrument collection data to transmit it to computer use after serial port; use C#2005 and SQL to build software platforms to complete real -time data reading, data computing and data storage, historical data query, and real -time curve drawing, and realize the flow of flow volume.

2. Technical parameters

Flow range: 1 ～ 10m3/h

Pressure: 1.6MPa

Medium: water

Instrument measurement accuracy: level 0.5

Power: 440V 16A

Third, system composition

The experimental system consists of a waterway system, an electronic weighing unit, a data collection system, a computer measurement control system, and a calibrated flow meter.

Fourth, working principle

(1) Open the m--n valve 2, open the circulating water pump 1, and adjust the height of the overflow valve 3, so that the high level water tank 4 is at a cert--n water level, adjust the proportional valve 7, thereby ensuring that the water flow in the waterway system is stable.

(2) Open the water inlet valve 16 and the water outlet valve 15 of the weighing cylinder 18 to confirm that the water valve flows out;

(3) Open the liquid valve 14 and close the water inlet valve 16 of the weighing tube. After the water flows in the water tank, the water outlet valve 15 is closed.

(4) Turn off the liquid valve 14 and 15, and open the water tank water inlet valve 16 at the same time. At this time, the system constitutes a loop;

(5) Operation on the computer, start detection, and expl--n the specific software operation in the software part;
