Introduction:
The ultrasonic core module uses a pair of ultrasonic sensors installed upstream and downstream to calculate the flow velocity of the gas medium using the propagation time difference of the ultrasonic signals in the forward and backward flow directions in the gas medium, and then calculate the instantaneous flow rate and the accumulated flow rate. Features:
1. Small size, high precision, meet the accuracy requirements of 1.5;
2. No mechanical moving parts, not easy to corrosion, low pressure loss;
3 powerful, comes with temperature / pressure measurement to meet the different needs of customers;
4. Instantaneous output of direct flow, convenient for secondary development;
5. Easy to use, easy to install;
6 interface is simple, and external use UART / TTL interface connection;
7. Thanks to the excellent structure, the flow field of the sensor is stable and can pass strict
8. Pollutant experiment
