air flow meter

air flow meterIt is an induction instrument that measures the volume flow rate of conductive medium inside a tube based on Faraday's law of electromagnetic induction, using embedded technology with a microcontroller.air flow meterWhile meeting on-site display requirements, it can also output 4-20mA current signals for recording, regulation, and control purposes. It has been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, pharmaceuticals, papermaking, and water supply and drainage. In addition to measuring the flow rate of general conductive liquids, it can also measure the volumetric flow rate of liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids.

Performance characteristics:

1. The instrument structure is simple, reliable, without moving parts, and has a long working life.
2. No flow blocking components, no pressure loss or fluid blockage.
3. No mechanical inertia, fast response, good stability, can be applied to automatic detection, adjustment, and program control systems.
4. The measurement accuracy is not affected by the type of measured medium and its physical parameters such as temperature, viscosity, density, pressure, etc.
5. Different combinations of PTFE or rubber lining materials and electrode materials such as Hc, Hb, 316L, Ti can adapt to the needs of different media.
6. There are various flow meter models available, including pipeline type and plug-in type.
7. Using EEPROM memory, the storage of measurement and operation data ensures safety and reliability.
8. It has two types: integrated and separated.
9. High definition LCD backlit display.
