How to setup a zero point calibration ?
It is necessary to establish the true zero flow condition and program that set point into the instrument. If the zero set point is not at true zero flow, a measurement difference may occur. Because every flow meter installation is slightly different and sound waves can travel in slightly differen...Read more -
How to judge the liquid flow direction for our flow meter ?
Make sure that the instrument works properly Check the flow rate for the indication. If the displayed value is positive, the direction of the flow will be from the UP transducer to the Down transducer; if the displayed value is negative, the direction will be from the Down transducer to the UP tr...Read more -
Temperature sensor installation
(a) 6.2.1 CLAMP-ON TEMPERATURE SENSOR When determining the installation position of temperature sensor, we should pay attention to the pipeline surface. Pipeline surface must be clean before installing temperature sensor, then use belts to fix temperature sensor. (b) 6.2.2 INSERTION TEMPERATURE S...Read more -
