How to adjust the flow rate of electromagnetic flowmeter

Firstly, enter the password of the electromagnetic flowmeter to enter the menu, and find the caliber column. For example, what is the caliberDN50， At this point, if you want to increase the traffic, change the caliber from DN50 to DN65, and naturally its traffic will be larger than that of DN50.

Secondly, there is another method of adjusting traffic, which is to enter the password to enter the menu and findIn the K coefficient column, for example, if the K coefficient is 1.065, if you want to increase the flow rate by a large K coefficient value, the larger the value, the greater the K coefficient, and at this time, the flow rate will be larger.

How to debug electromagnetic flowmeter

Before debugging, our electromagnetic flowmeter should undergo a thorough inspection of the pipeline and flowmeter, including cleaning of pipeline debris. Oil medium pipelines do not require drying treatment. The inspection before debugging also includes the inspection of electrical circuits. Firstly, the connection of the circuit should be checked to ensure reliable grounding before conducting other circuit tests and inspections to avoid capacitive effects on the circuit, stored electricity, or damage to the instrument caused by measuring power supply. In addition, insulation resistance and grounding resistance tests are also required.

Water commissioning: Whether it is an instrument for measuring aqueous suspension or oily media, the electromagnetic flowmeter should simulate the actual temperature, pressure, flow rate and other conditions of the measured medium for water commissioning before formal commissioning. If any abnormalities or missing parameters occur during the water test, the instrument should be tested individually or sent to the production unit for calibration.

System investigation test: After completing the single function water test and the preparatory debugging of the control host, the electromagnetic flowmeter can proceed with system debugging. Oil medium pipelines need to be dried before the tested medium can be introduced for system operation. During system debugging, the host should pre code and scan each measurement point to ensure that all instrument components are in normal working condition before proceeding with functional debugging. During functional debugging, the host system reads parameters and performs critical value alarm tests on each instrument, then writes control data, performs debugging one by one, and sends relevant data to the relevant upper computer for analysis.

How to set parameters for electromagnetic flowmeter

Usually, the parameters of an electromagnetic flowmeter need to be set, but many people are not sure how to set its parameters. Now let me briefly explain how to set the parameters of an electromagnetic flowmeter. The general parameters are set within a certain range, and there are certain differences among different manufacturers. This is based on the product manual, and the electromagnetic flowmeter sensor makes judgments by measuring the fluid resistivity value in real time. Whether the pipeline is in a full state or not is a continuous value in the measurement of the empty pipe, although different fluids have different electrical resistivity values to determine. Whether the flowmeter pipeline is in a full state is a continuous value in the measurement of the empty pipe. Although different fluids have different electrical resistivity values, as long as the fluid is in a full pipe state, its electrical resistivity value is stable.
