Thermal gas mass flow meter scale installation and maintenance

Abstract: the thermal type gas mass flowmeter scale installation and maintenance of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Thermal type gas mass flowmeter is using the heat conduction principle measuring instrument of fluid flow. The instrument adopts the method of constant temperature difference for accurate measuring gas flow. With small volume, high degree of digital, easy installation, measurement accuracy, etc. The sensor units. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a thermal type gas mass flowmeter scale installation and maintenance of the article details. Thermal type gas mass flowmeter is using the heat conduction principle measuring instrument of fluid flow. The instrument adopts the method of constant temperature difference for accurate measuring gas flow. With small volume, high degree of digital, easy installation, measurement accuracy, etc. The sensor part consists of two level benchmark platinum resistance temperature sensor. Adopt bridge type circuit, a fluid temperature sensor measurement, another sensor to maintain higher than that of fluid temperature of constant temperature difference, but under the condition of high temperature and high pressure flow rate measurement. Thermal type gas mass flowmeter installation and connection of 1, a size installation and connection requirements (1) if converter installed on the outside, need to add instrument box, avoid rain and sun. 2 ban installation in the case of strong vibration, installed in a large number of corrosive gas environment. (3) don't and frequency converter, electric welding machine and other pollution of power supply equipment Shared an ac power source, when necessary, the purification for converter equipped with power supply. (4) a body plug-in should be inserted to the pipe axis to be tested, so the measuring rod length depending on the measured pipe diameter size, an order should be specified. If can't insert to the pipe axis, the calibration coefficient will be provided by the manufacturer, in order to achieve accurate measurement. 5] a size pipe sections of the flange connection, in line with the national standard GB/T9119-2000. 2, the installation of thermal type gas mass flowmeter (1) a plug-in installation size is provided by the manufacturer pipe fittings and valves. Not welded pipe, provided by the manufacturer pipe clamp. For example, can be welded pipe. Fittings and pipe welding first, then install the valve, and specialized tools, drilling zui after instrument installation. Remove the instrument maintenance instrument,, close the valve and will not affect the normal production. 2 pipe sections of installation should choose appropriate standards flange connection. (3), when installation should pay attention to instrument & logo on the other; Medium flow direction mark & quot; To be the same as the actual flow direction of the gas. 3, thermal type gas mass flowmeter on the debugging and operation instrument potential into the measuring condition, namely, must according to the actual working condition of the input data. 4, thermal type gas mass flowmeter maintenance (1) open the chassis, be sure to first power. Demolition of a sensor, pay attention to the pipeline pressure, temperature or gas has non-toxic. (3) sensor is not sensitive to small amounts of dirt, but when used in a dirty environment, also should be cleaned regularly. Otherwise will affect the measurement accuracy. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

mass flow meter are all following the most compatible manufacturing regulations.
