Notes:
∗3 Valve sensor is the temperature and pressure sensors mounted onto the valve (Model FVY5130J/FVY5140J/FVY5150J), measuring valve
surface temperature and inlet and outlet flow pressure.
∗4 When you test the withstand pressure of the valve sensor manufactured on and after Nov. 1, 2011 (date code: 1144 or greater), up to
1.6 MPa pressure can be applied to the valve sensor.
∗5 The above pressure measuring accuracy is for the 7 °C to 65 °C flow temperature. If the flow temperature is out of the 7 °C to 65 °C range,
the valve sensor flow measuring accuracy may lower.
∗6 For accurate measuring of flow temperature, thermal insulation is required. Refer to the subsection Heat insulation for applying thermal
insulation.
∗7 Overall accuracy is calculated based on the sensing accuracy of the temperature sensors connected, the conversion accuracy, and the
error due to wiring length.
∗8 Energy calculation accuracy is calculated from the flow measuring accuracy at 1 °C measuring error of the temperature difference.
∗9 The flow measuring accuracy in the table corresponds to the data shown in the above flow measuring accuracy graph.
