GERAND FIRE PUMP TEST FLOW METER

Gerand Engineering Company was founded in 1965 by a qualified team of engineers with years of experience dedicated to providing outstanding quality products for hydronic balancing in the HVAC industry..

Gerand’s product line consists of Venturis, Indicators (orifice type) and Balvalve-Venturis (one-piece unit, fixed Venturi and valve) manufactured by Gerand and meters used to balance the hydronic and air systems.

Venturis and Indicators are furnished with a set of meter fittings (nipples, valves and quick disconnects). Balvalve-Venturis have nipples and quick disconnects.

A chained metal tag is furnished with all flow devices. The tag shows the unit size, unit location, the GPM and corresponding meter reading in inches of water ().

Gerand suggests using Venturis on all units at least 2-1/2" and larger for ultimate accuracy and lowest possible head loss. Orifices may also be used though the permanent head loss, with orifices is substantially increased from that of Venturis.

On 1/2" through 2" lines we recommend using Balvalve-Venturis furnished as a one-piece Venturi/valve with a memory lock on the handle.

All flow fittings should be supplied with chained metal tag indicating the unit size, unit location, GPM and corresponding differential reading in inches of water. Venturis and indicators should be supplied with nipple, valve and quick disconnect meter fittings. Balvalve-Venturis should be supplied with nipples and quick disconnects.

A portable 0-50" or 0-100" differential meter shall be used for balancing flow in all  units. Meter should be furnished as part of the system.
