Electromagnetic flowmeter measurement, electromagnetic flowmeter is the use of electrodes and fluid composed of a circuit to measure the circuit caused by the main electrical parameters.Traditional electromagnetic flowmeter for low conductivity can not be accurately measured, and more sensitive to friction, adhesion effect, only to measure fluid mechanics full tube condition, so it must be changed its structure, so that it can be integrated into the more complex natural environment.The key way to change the structure of the electromagnetic flowmeter is to change the total number and position of the electrical stages, thus generating capacitive electromagnetic flowmeters, non-full tube electromagnetic flowmeters, etc.

Electromagnetic flowmeter measurement

1, accuracy level and function according to the measurement requirements and application occasions to choose the accuracy level of the instrument, to ensure economic and cost-effective.For example, for the purposes of trade settlement, commodity transfer and energy measurement, a higher level of accuracy, such as class 1.0, class 0.5, or higher, should be selected;Used for process control, select different precision levels according to control regulations;Some are just to check the whole process flow, do not need to do ** control and metrological verification occasions, can choose a slightly lower level of accuracy, such as 1.5, 2.5, or even 4.0, at this time can be used with high quality and cheap plug-in electromagnetic flowmeter.

2. When measuring material flow rate, measuring range of instrument panel and specification of general material, the full flow rate of electromagnetic flowmeter can be used within the range of measuring material flow rate 0.5-12m /s, with a wider scope.Choose the dashboard specifications (specifications) not necessarily and processing line, the same shall consider measuring total flow field is in the range of flow velocity, namely when the pipe line velocity of slightly lower, do not consider traffic or to the velocity measurement accuracy under the provisions of the instrument can not make sure, must reduce the dashboard specifications, and flow velocity in the riser, the measurement results are satisfied.

3. Avoid ferromagnetic objects and machines with strong magnetic fields as far as possible to prevent electromagnetic fields from endangering the working electromagnetic fields and total flow signals of the controller.

4, should be installed as far as possible in the dry natural ventilation place, to prevent wind and sun, the working temperature should be in -20 ~ +60℃, air humidity is lower than 85%.

5. There should be sufficient indoor space around the electromagnetic flowmeter, which is conducive to inspection and maintenance.

Porcelain city Shanghai instruments co., LTD., the introduction of Germany Siemens numerical control processing center, make the tiny flowmeter is greatly increased, actually has reached world leading level, such as OVAL LSF40, many clients in Japan and the customer to know LSF40 flow range in 0.7 ~ 50 l/H, and porcelain xian CX - M5 - AL can achieve 0.3 ~ 60 l/H, the same 0.5% FS precision, another porcelain city gear is SS316L is qualitative, OVAL gear is plastic.
