Overview
The YA-330 flow meter consists of an S-type pitot tube, a thermistor, a micro differential/absolute pressure sensor group, a blowback unit, and a signal control processor. It is an integrated flow rate, dynamic pressure, static pressure, and smoke temperature monitoring instrument developed specifically for high dust, high temperature, high humidity, and high corrosion environments in flue gas emission monitoring. It meets the requirements of relevant national standards and is suitable for real-time continuous measurement of flue gas flow rate, pressure, temperature, and flow rate in continuous emission monitoring systems (CEMS).
Product Details
YA-330 flowmeterThe temperature pressure flow monitor (hereinafter referred to as the temperature pressure flow monitor) consists of an S-type pitot tube, a thermistor, a micro pressure difference/absolute pressure sensor group, a blowback unit, and a signal control processor. It is an integrated flow rate, dynamic pressure, static pressure, and smoke temperature monitor specially developed for high dust, high temperature, high humidity, and high corrosion environments in flue gas emission monitoring. It meets the requirements of relevant national standards and is suitable for real-time continuous measurement of flue gas flow rate, pressure, temperature, and flow rate in continuous emission monitoring systems (CEMS).
Technical features:
Real time measurement of flue gas flow rate, upper and lower differential pressure, and temperature, with active output of 4-20mA through 3 isolated analog signals.
Automatic timing or manual zeroing of dynamic pressure and flow rate.
High measurement accuracy, good reliability, and can work continuously for a long time.
The split structure and pitot tube have a 300mm expansion and contraction adjustment range.
Clean the particles inside the pitot tube, and the interval time for blowback can be set.
Easy installation and wiring, low maintenance.
