Product Description:
The CMF9019 Maximum Flow Size Selection (SLPM) 300,500,600,800,1000 is composed of MEMS flow sensing unit and high-precision digital processing and calibration circuit (MCU). Integrated Δ-δA/D converter, logic circuits with internal calibration functions, MCU processors and display unit modules, etc. The sensing signal was effectively collected in real time, obtained accurate traffic signals, and processed corresponding compensation algorithms internally. The test principle of traffic meter determines that without any external calibration compensation, it can ensure high -precision traffic output; friendship Digital output communication methods, users can easily use digital communication to obtain corresponding rich data information; product applications are very broad.
Features:
- • A variety of output methods can actively upload data through the communication interface or query the output data from the upper machine, or the linear analog signal of the output interface can be output;
• LED display instantaneous flow and cumulative flow. Support the on -site operation to operate the flow of flowmeter meters:
• High stability, high accuracy and excellent repetitiveness of full measurement:
• The connection method is thread, which is easy to install and use;
• High sensitivity, very small starting flow;
• Multi -sensor integration is implemented on a single chip to make the range ratio of 100: 1 or even higher:
• The sensor has a high impact resistance and has a good ability to resist condensate;
• The sensor chip is measured by thermal quality flow, and no temperature pressure compensation is required to ensure the high -precision metering of the flowmeter;
•quick response;
• Zero -point stability is high;
• Low power consumption, low pressure loss;
