4.Open the isolation valve and insert the drill through the valve and cut the sensor clearance hole. After the hole is cut, withdraw the drill from the isolation valve and close the valve. Remove the drilling machine per manufacturer's instructions.
make sure bleed valve clears isolation valve handle

5.Install brass sensor nut/bleed valve into the top of the isolation valve. Make sure the bleed valve clears the handle of the isolation valve during operation.

I.D.: ________________
For standard sensor installa- tions, the ruler may be used to measure wall thickness and I.D. of pipes up to 5 inches in diameter.
3.5 Calculating the H Dimension
Before installing the sensor some critical dimen- sions must be established. The rotor shaft must be located 10% inside the pipe I.D. to insure accurate calibration capability. To accomplish this, the "H" dimension is measured from the outside surface of the pipe to the bottom of the sensor flange.
Nominal "H" dimensions for standard pipes are listed on page
