The direct insert style liquid flow sensor with stainless steel/PPS plastic tip combines flow sensing with a built-in transmitter for an all in one flow measuring system. This device fits all 1-1/2 to over 36 in pipes, and it is intended for direct installation into the pipe through a 1 in NPT hole. In the hot tap installation, the sensor is mounted in the pipe under pressure by attaching a service saddle or weld-on fitting to the pipe. Then sensor is attached to an isolation valve and extended into the pipeline to measure flow. Hot tap installations are often required in retrofit projects, but even in new construction
