Air Balance Store :: Water :: Hydronic Manometer

Facilities containing hydronic (water) systems are typically balanced for terminal flow using differential pressures. Balancing hydronic systems reduces energy consumption and saves money.

The Alnor® Hydronic Manometer Model HM670 and the Alnor® Hydronic Manometer Model HM680 are used to balance hydronic heating and cooling systems and to check pump performance. Both models can measure and display differential, high side, and low side pressures simultaneously without the need to change hose connections or instrument valve settings.

The Alnor® Hydronic Manometer Model HM680 can also display volumetric flow when a Cv (Kv) factor is programmed. Up to 100 Cv (Kv) factors can be entered. In addition, the HM680 can calculate brake power, heat
flow, Cv (Kv) factors and impeller sizing. Up to 1,000 data points can be stored to memory for later recall or downloaded to a PC using CompuDatTM USB software and USB interface cable.
