DPV Differential Pressure Air Flow Transmitter
The DPV Multi-function Airflow Velocity/Volume Transmitter is designed to measure airflow in ventilation and air conditioning systems. It determines the speed and amount of air movement by measuring the difference in pressure using flow sensors such as average flow measurement blades (AFMB), L-type pitot tubes, or S-type pitot tubes.
This transmitter is designed to take accurate measurements, even with variations in temperature. It's also built to resist interference from electrical noise commonly found in industrial settings. This makes it a reliable tool for measuring airflow in a range of environments.
The transmitter offers a variety of measurement ranges and units, and it provides different output options. It also includes protection against electrical problems, ensuring dependable operation. An optional remote sensor can be added to measure and adjust for temperature. A display screen and buttons allow users to calibrate the device, change units, set response time, choose between air velocity or volume measurement, and adjust other settings. The device is designed to be durable and protected against dust and moisture.
