Technical characteristics
JNYQ-TPF-01 Temperature, Pressure, and Flow Integrated Monitoring Instrument
The temperature, pressure, and flow monitoring instrument uses the Pitot tube method to measure the flow velocity of flue gas. The Pitot tube, pressure sensor, and temperature sensor are used to measure the dynamic pressure, static pressure, and temperature of the flue gas. These parameters are proportional to the measured flue gas flow velocity, and can be used to quantify the flow velocity of the flue gas.
Detailed description
• It can measure the flow rate, dynamic pressure, static pressure, and temperature of flue gas in real time, and actively output 4-20mA through 4 analog signals.
• Automatic timing or manual zero calibration of dynamic pressure and flow rate.
• LCD displays various measurement data and signals, which can be directly read for easy debugging.
• High measurement accuracy, good reliability, and can work continuously for a long time.
• The split structure and pitot tubes have a 300mm adjustable range for expansion and contraction.
• Equipped with an automatic backwash unit, it can regularly clean the particles inside the pitot tube, and the backwash interval time can be set.
• Equipped with an air tank, ensuring sufficient pulse back blowing air for effective blowing.
• Easy installation and wiring, low maintenance.
• Small size, compact structure, and requires small installation space.
Measurement principle and structure
The temperature, pressure, and flow monitoring instrument uses the Pitot tube method to measure the flow velocity of flue gas. Using Pitot tubes, pressure sensors, and temperature sensors to measure the dynamic pressure, static pressure, and temperature of flue gas, these parameters are proportional to the measured flue gas flow rate, thus allowing for quantitative measurement of the flue gas flow rate. The S-type pitot tube and armored thermistor are made of 316L stainless steel material with high corrosion resistance, and are combined with a 316L stainless steel protective sleeve and a fixed outer nut to form an integrated pitot tube and temperature probe.
