The best thing to happen to hydrant flow testing has arrived at USABlueBook! In use for several years by the Irish and UK fire brigade, this advanced yet simple-to-operate flow tester features an electromagnetic flow meter, ensuring that nothing comes in contact with the water.
Extremely accurate, with ±4 gpm accuracy throughout the range, the Flowmaster 250 reads static pressure, dynamic pressure, instantaneous flow and total flow. The meter gives a digital readout of flow and has a totalizer function as well. A high-quality bourdon tube pressure gauge shows the pressure output on a 2-1/2" dial.
This lightweight unit offers standard 2-1/2" NST fittings to hook directly to the hydrant. Hard anodized aluminum body offers long life and durability. An internal rechargeable battery allows continuous use up to 6 hours between charging. Sturdy handle provides ease of installation and great portability.
