    i directly attach meter to  pipeline which is bought from audiowell HS 0014-000 (which image also in attach and this model info easily found on internet.)

    Is any glue want to stick on sensor or any setting want to change. please guide us.

    Ashitosh,

    The audiowell based water sensor that you have attached apparently has internal circuitry in it which has help in detect the water flow rate. Am not too sure why you have connected TDC1000EVM with this.

    We recommend you use the MSP430 based ultrasonic flow metering device which has good accuracy & resolution in measuring water/gas flow.
