Electromagnetic flowmeter NSC100

Product Overview

NSC100 electromagnetic flowmeter is an electromagnetic induction flow meter, which is divided into two categories: on-site display type (integrated type) and remote display type (split type)

Product Features

• Highly intelligent and precise;
• Can measure forward and reverse flow rates, display instantaneous flow rate, cumulative flow rate, flow rate percentage, conductivity ratio;
• The range ratio can reach 1:150;
• Long transmission distance (split 100m);
• Full dot matrix Chinese display, range can be set freely;
• Sensors and converters can be freely interchanged in direction, and the upper and lower limits of the flow rate of the excitation fluid in the air tube are alarmed;
• Easy to use, minimal maintenance, and long service life;
• Low power consumption (10V) can simultaneously output standard current and frequency pulses, as well as RS-485 communication.

Product Overview

• Measurement medium confirmation
• Range confirmation
• Confirm the requirements for implementing functions and displaying parameters
• Confirmed by Tongyuan Transmission
• Confirmation of special requirements such as high temperature, corrosion resistance, wear resistance, and waterproofing.

For example, the flow rate of the medium measured by a general industrial electromagnetic flowmeter should be 2-4m/s. In special cases, the minimum flow rate should not be less than 0.2m/s and the maximum should not be greater than 8m/s. If the medium contains solid particles,
The commonly used flow velocity should be less than 3m/s to prevent excessive friction between the lining and the electrode; For viscous fluids, the flow velocity can be chosen to be greater than 2m/s. A higher flow velocity helps to automatically eliminate the effect of viscous substances attached to the electrode, which is beneficial
To improve measurement accuracy. Under the condition that the range Q has been determined, the size of the flowmeter diameter D can be determined based on the range of flow velocity V mentioned above, and its value can be calculated by the following formula:
Q = πD2V/4
Q: Flow rate (㎡/h) D: Inner diameter of pipeline V: Flow rate (m/h)
The range Q of the electromagnetic flowmeter should be greater than the expected maximum flow value, while the normal flow value should be slightly greater than 50 of the flowmeter’s full-scale scale.
