Installation for Hot tap models
The insertion depth and alignment of the sensor are critical to the accuracy of the flow measurement. The impeller
must be at the same location in the pipe as it was during calibration. Data Industrial provides sensors with three dif-
ferent stem lengths. Longer stems are intended for use in larger diameter pipes and shorter stems for use in smaller
pipelines. However stem length has no affect on the operation of the sensor provided that the impeller is positioned
correctly in the center of the pipe.
Stem length H1 is intended for use in nominal pipe diameters from 1 1/2” to 10”, H2 is for nominal pipe diameters from
12” to 36”, and stem length H3 is for nominal pipe diameters from 36” and up. However, pipe with extra thick walls,
existing linings, or unusual tapping hardware may require longer length sensors - Consult factory.
