The shape of the flow meter and the precautions for use

Abstract: The information on the shape and use of the flow meter is provided by the excellent manufacturers of flow meters and flow meters. 1. When the user selects the model, the model and specification of the flowmeter should be reasonably selected according to the nominal pressure of the pipeline, the maximum pressure of the medium, the temperature of the medium, the composition of the medium, the flow range and the signal output requirements. 2. In order to make the best performance of the flowmeter, the flowmeter should be More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article on the shape of flowmeters and precautions for use. 1. When the user selects the model, the model and specification of the flowmeter should be reasonably selected according to the nominal pressure of the pipeline, the maximum pressure of the medium, the temperature of the medium, the composition of the medium, the flow range and the signal output requirements. 2. In order to make the best performance of the flowmeter, the flow range of the flowmeter should be within the range of (20% to 80%) Qmax. 3. The signal output mode of the flowmeter when it leaves the factory: pulse signal output (LWQ basic type), on-site display (LWQ-B lithium battery power supply), on-site display (LWQ-C4-20mA) If other output functions are required, please place an order time description. ?Maximum leak detection pressure for medium and low pressure gauges:≤1.0Mpa, the temperature and pressure compensation type leak detection pressure does not exceed 3 times the upper limit of the pressure sensor. The high-pressure gauge case is leak-detected at a pressure of 1.2 times the rated flow. ?Precautions for the use of the flowmeter: After installation, the leak detection and installation and use should comply with the following regulations: ①Close the outlet valve and the inlet valve first. ②Slightly open the outlet valve, then slowly open the inlet valve, so that the watch starts slowly, and then slowly open the outlet valve to achieve normal operation, to prevent sudden start and damage to the watch movement. ③ When the gas is stopped, the outlet valve should be closed, and then the inlet valve should be closed. ?After the flowmeter is installed and used, do not touch the fasteners such as bolts, screws and nuts at will, so as to avoid the danger of air leakage and damage. ?The flow meter movement (clean air) should be cleaned and maintained every six months; (dirty air) should be cleaned and maintained once a month. ?If the movement is put into use again after being disassembled and repaired, it is necessary to carry out a sealing test according to the maximum pressure. And inject T4 precision instrument oil or transformer oil into the movement. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Modeling and Precautions for Use of Flow Meters'

There are a lot of businesses today that are very much in demand and one of them is a mass flow meter.
