Advantages of frozen water detection in electromagnetic flowmeter
The advantage of frozen water detection of electromagnetic flowmeter, we all know that for accurate measurement of liquid to choose the actual effect of the most appropriate is the electromagnetic flowmeter, the first is the internal problem of electromagnetic flowmeter, pay attention to the memory to bear the negative pressure problem.When the precise measurement of the material has a certain corrosion, we should choose teflon ethane memory materials.However, the electromagnetic flowmeter using tetrafluoroethylene raw materials can not bear negative pressure.There are two solutions to the problem:
1. Change the original vent valve into a one-way valve (check valve). In case of slight negative pressure in the pipeline, the check valve will automatically open to inhale air from the atmosphere, thus ensuring safety.
2. Choose the memory with skeleton, the disadvantage is to increase the investment cost.
The above is the electromagnetic flowmeter in refrigerated water in the accurate measurement of matters to pay attention to.Another flowmeter suitable for cold storage water metering is the time-difference ultrasonic flowmeter, in the selection of the same to pay attention to some problems.For example, since the sensor and the cable plug may be wrapped in the insulation layer, in order to prevent the sensor from being damaged by condensation, the protection level of the cable plug shall be IP68 submersible protection level.
Shanghai porcelain has a lot of technology accumulation, so it can also customize the flow meter according to customer requirements. The design department can interact within 3 weeks, which is even faster than the delivery time of foreign standard flow meters.Major application areas include metrology, hydraulic or supervisory technology, filling, glue or the monitoring of mixing ratios in a variety of industrial sectors.Shanghai porcelain flow meters are used in plastics, polyurethane, chemical, pharmaceutical, paint and coatings, hydraulic and automotive processing plants and two-component processes worldwide.
