The Bard 8603-041 is an OEM water flow meter used on select Bard HVAC water source and geothermal style systems to verify and set proper water flow through the unit heat exchanger. This meter installs inline with 1 inch female pipe thread connections and provides an at-a-glance flow reading that helps technicians confirm the system is operating within the required GPM range for stable heating and cooling performance. Replacing a worn or inaccurate flow meter with the correct Bard 8603-041 helps restore reliable commissioning and troubleshooting, especially when addressing low flow lockouts, poor capacity, or nuisance temperature faults caused by improper water circulation.
