Electromagnetic flowmeter standard, electromagnetic flowmeter is widely used in wastewater, fluorine chemical industry, manufacturing tap water, drinking water manufacturing industry and pharmaceutical industry, steel and many other aspects.Because the rationale dictates that it only measures the conductivity of the liquid.Although it is much better than other types of flowmeters in terms of dependability and reliability.

Electromagnetic flowmeter standard

Standard and technical specification for metrological verification of electromagnetic flowmeters

EMF has two international standards, the standard is IS06817 and IS09104, the first is the use of standards, the second is the characteristics of the identification standards;Chinese standard has the instrument equipment instrument technical professional standard ZBN12007, is the commodity standard, has been formulated and is equivalent to the choice of international standards of 2 national standards.National standards for excellent industrial production are BS5792 from the United States and nsB7554 from Japan.Japanese standard

In the application level of the elaboration, is very "explanation" part of the use of instruments to assist.

JJG198 is the technical specification for universal metrology verification of rate and total flow meters in China. Although EMF is also applicable, it seems simple, while IS09104 is more detailed.

ISO/CD13359 is a developed requirement for spacing between flanged flow sensor flange plans.

maintenance

Just visualize the meter regularly, check the surrounding environment of the meter, clean the dust, ensure no leakage and other chemicals, check the wiring is good, check whether there is a strong electromagnetic field machine around the meter or there is a cable across the meter.If the accurately measured material is very easy to dirty electric level or in the accurately measured wall thickness settling, scaling, scaling should be done on time, cleaning.

Common faults

Beginning of flowmeter putting-in-service proactively or normal putting-in-service proactively after a period of time detect anomalies in the instrument work, should be the first to examine flowmeter external condition, such as switching power supply is not good, line is leak or in the full package, if there are any bubbles in the pipeline, shielded cable is damaged, converter output data signal (i.e., after the instrument type control circuit) is the way.Remember to follow the flow meter blindly.
