Electromagnetic flowmeter negative pressure solution, electromagnetic flowmeter characteristics are stable, widely used, in the pharmaceutical industry, food industry, biological engineering and other health regulations are the back of the electromagnetic flowmeter.However, in the whole process of feedback with the user on the spot, the professional and technical personnel found that there would be some factors existing in the actual working conditions that would harm the measurement, but could not exceed the user's expectation.The following porcelain flow meter technology xiaobian on the electromagnetic flow meter can not accept the solution of negative pressure to share with you to do a detailed solution.
Electromagnetic flowmeter attaches great importance to the advantages of water test in freezer: you know: no pressure loss, accuracy, good stability.However, due to the composition of refrigerating chamber cement, some reasons should be paid attention to in the use of electromagnetic flowmeter.First is the electromagnetic flowmeter inside the village reason, pay attention to the memory to accept the negative pressure reason.When measuring medium has a certain corrosivity, we should use polytetrafluoroethylene video storage material.But the electromagnetic flowmeter using tetrafluoroethylene material cannot accept negative pressure.
There are two ways to solve the problem of electromagnetic flowmeter:
1, the original vent valve into a one-way valve (check valve), in the pipeline micro-small negative pressure, check valve automatically open, from the air inhalation, so as to ensure safety.
2, the use of skeleton type video memory, the disadvantage is to increase the cost of investment.
Porcelain city of all flowmeters, small to a screw hole, large to the case and gear are using Germany Siemens CNC machining center to complete, completely get rid of the current domestic mechanical and manual mixing operation of the manufacturing process, elliptical gear manufacturing process will produce a milestone change.
