Успешное применение электромагнитного расходомера для измерения расхода на бумажной фабрике

Для бумажных фабрик более важны измерение и контроль расхода. Измерение потока целлюлозы, поступающей на бумагоделательную машину, может использоваться в качестве перенаправления для количественного контроля бумаги в сочетании с измерителем концентрации. Измерение количества целлюлозы в системе варки может...

For paper mills, flow measurement and control are more important. Measuring the pulp flow entering the paper machine can be used as a feedforward for paper quantitative control in conjunction with a concentration meter. Measuring the pulp in the pulping system can achieve continuous or intermittent control of the pulp ratio. For many papermaking companies, electromagnetic flowmeters are used for flow measurement of many media such as pulp, alkali liquor, source liquid, black liquor, etc., which can fully meet the use requirements and are economical.

With the increasing maturity of electromagnetic flowmeter measurement technology and the increasing cost-effectiveness, electromagnetic flowmeters have become more and more popular with papermaking companies.

After talking about the successful application of electromagnetic flowmeters in flow measurement in paper mills, let's talk about some precautions for its installation.

The electromagnetic flowmeter should be installed as far away from the vibration source and electromagnetic interference as possible. The transmitter can be installed vertically, horizontally, or tilted, but the full pipe condition should be guaranteed, that is, it should be installed in a place where the measuring conduit can be filled with liquid at any time. When installed vertically and tilted, the liquid should flow through the instrument from bottom to top. When installed horizontally, the two electrodes should be on the same horizontal plane.

Since the signal of the electromagnetic flowmeter is weak, the transmitter housing, shielding wire, measuring conduit, and pipes at both ends of the transmitter must be grounded, and a separate grounding point should be set. The converter part has been grounded through the cable, so it does not need to be grounded again to avoid interference due to different ground potentials. The signal line and the excitation line should be laid separately, and avoid parallel arrangement of the two.

Electromagnetic flowmeters are used in our company, with accurate and reliable measurement, stable operation and easy maintenance. It is indeed the best choice for papermaking enterprises to measure the flow of pulp, chemical raw materials, black liquor, sewage, etc. The above is the relevant content about electromagnetic flowmeters compiled by Beite editor.
