Nanjing Hanhua Fluid Technology Co., Ltd

Electromagnetic flow meter.

Brand: Hanhua.

Series: NCF-EM Series.

Product introduction:
According to Faraday's law of electromagnetic induction, conductive liquids flow within a magnetic field to generate induced electromotive force. When the conductive liquid flows through the electromagnetic flow meter, the inductive electromotive force can be detected between the electrodes, the inductive electromotive potential size is directly related to the conductive medium flow rate, the magnetic induction strength of the magnetic field, the width of the conductor (flow meter measuring the inner diameter of the tube), and the media flow within the tube can be obtained by operation. Hanhua NCF series electromagnetic flow meter is a high precision, high reliability, multi-functional, miniaturization and low energy consumption of speed flow meters, widely used in thermal, electric power, steel, petroleum, chemical, food, paper, water treatment, municipal, environmental protection and other industries.
An introduction to performance.
NCF series electromagnetic flow meter is suitable for conductivity greater than 5uS/cm conductive medium, publicly called wide diameter range, with a variety of power supply methods, a variety of signal output, the use of standard RS-485 serial communication interface, support the international standard MODBUS-RTU communication protocol and GPRS and other wireless and wired communication network mode, with cumulative pulse equivalent output. Provides wireless meter reading systems (computer management software and databases) that can be accessed over remote networks.
1, functional features.
The NCF-EM series of electromagnetic flow meters offers excellent measurement repeatability and linearity, good reliability and anti-jamming performance, good pressure sealing, low-pressure loss measuring tubes, high intelligence and maintenance-free performance.
2, the occasion overview.
NCF-EM series electromagnetic flow meters are suitable for normal, non-open-air use, high measurement accuracy, not easily disturbed, easy to install, high temperature, open-air or special use environment, applicable sensors need to be immersed in water, in line with explosion-proof requirements.
To meet the requirements of different media measurements, the lining and electrode materials of the sensor can be selected in a variety of ways.
