USER GUIDE
Item#: INPN2, INPN1.75, INPN1.125, INPNK
OVERVIEW
The In-line Pitotless Nozzle can be used for: stairwell standpipe flow testing, pressure reducing valve flow
testing, fire pump flow testing, fire flow testing of hydrants, or as an in-line flow meter for fire pumps. The
device connects to 2 ½” outlets. Hose or piping can be attached downstream of the unit without affecting the
accuracy of the readings. The In-Line Pitotless Nozzle determines flow-rate by measuring the differential
pressure between the two gauge ports.
