The In-Line Pitotless Nozzle measures water flow-rate from a hose valve, pressure reducing valve, hydrant nozzle, between two lengths of 2.5” hose, or just about any 2.5” outlet. Hose or piping can be attached downstream of the unit without affecting the accuracy of the readings.
Common applications for the In-line Pitotless Nozzle include:
- Stairwell standpipe flow testing
- Pressure reducing valve flow testing
- Fire pump flow testing
- Fire flow testing of hydrants
- As an in-line flow meter for fire pumps.
The In-line Pitotless Nozzle Kit includes the following items configured in a padded case:
- Pitotless Nozzles™ (Threaded). Sizes 1⅛”, 1 ¾”, and 2”.
