Application
HVAC & Cooling Towers
Proper flow balance is critical to HVAC system efficiency. Flo-Gage meters provide reliable, direct-reading flow indication for chilled water, condenser water, and glycol systems.
Flow Balance & Energy Efficiency
Unbalanced chilled water systems are one of the most common causes of comfort complaints and energy waste in commercial buildings. Flo-Gage meters installed at air handling units, fan coil units, and cooling tower cells give commissioning engineers and facility managers the data they need to balance the system properly.
Our meters are factory-calibrated for water and are available with specific gravity corrections for ethylene glycol and propylene glycol solutions — critical for accurate readings in freeze-protected systems.
Key Features
- Calibrated for water, ethylene glycol, and propylene glycol solutions
- High Viscosity option (V) for glycol concentrations above 50%
- Sizes from 1/4" to 3" for any chilled water or condenser line
- 4-20mA transmitter for BMS and DDC integration
- NEMA-4X gasketed enclosure for mechanical room environments
- Direct-reading GPM dial — no power required for local indication
Typical Applications
Chilled Water AHU Coils
Verify design flow to each air handling unit during commissioning.
Cooling Tower Cells
Balance condenser water flow across multiple tower cells.
Glycol Heat Exchangers
Monitor glycol flow in process cooling and freeze protection loops.
BTU Sub-Metering
Pair with temperature sensors for tenant energy billing.
