Tiny gas flowmeter

Description :

MF series flow sensor technology and intelligent electronic control technology, specially designed for ordinary small amount of gas flow measurement developed product. The sensor can directly measure gas mass flow rate, low pressure loss. Applicable to purify air or nitrogen gas flow measurement, can also be used for environmental monitoring instrument, such as air sampling and analysis instrument 9 gc spectrometer) DFS/DMF flow sensor, pipe diameter is 3 mm, low cost, small pressure loss, measurement range to five biggest SLMP, suitable for particle counter and analysis instruments, etc. With RS - 485 interface DFS/DMF flow sensor, measurement range to 800 largest SLPM. Can be used for air flow measurement and control equipment. Application in the medical oxygen, clean gas measurement, such as: air sampler, gas analyzer, etc.

Features :

1. No mechanical moving parts, corrosion resistance, stable and reliable, long life, long running without special maintenance;

2. Using 16-bit single chip, high integration, small size, good performance, the whole machine function is strong;

3. The intelligent flowmeter flow sensor, microprocessor, pressure, temperature sensor, adopt built-in combination, make the structure more compact, can directly measure the fluid flow,  pressure and temperature, and automatic tracking compensation and real-time compression  factor correction;

4. Effective improve the double detection technology can detect the signal strength, and restrain the disturbance caused by pipeline vibration;

5. Using Chinese characters dot matrix display screen, display digits, more intuitive reading convenient, can be directly display the working status of traffic volume, the standard conditions, the total volume flow, parameters such as pressure, temperature and medium

6. Block using EEPROM technology, convenient parameter Settings, can be permanent, and can save up to a year of historical data

8. Cooperate with our company FM type data collector, can through the Internet or telephone network for remote data transmission;

9. The transmitter input pressure and temperature signal, strong interchangeability

10. The machine power consumption is low, can be used in batteries, also can be an external power supply
