WPD Turbine Water Meter - Hot
Whether for stand alone hot water metering or for use with the CF integrator as part of a complete Heat Metering System, Stream’s range of Turbine Hot Water Meters ensure a flowmeter for every application. From the standard ST/WEC - withstanding water to 130°C through the WP-QF for 200°C temperatures at pressures to 40Bar, to the WSD offering a vertical turbine for use in areas where straight pipe lengths may be difficult to achieve during installation.
