Tangshan card-type water meter price // Quotation for sales: Manager Gao Phone 1500-1377-453 Online QQ: 2817513962 Use the IC card to pay and recharge in the water meter management system to realize water usage, which is similar to other recharging items. The working principle of the water meter: A pair of temperature sensors are installed on the upward and downward pipes that carry the heat transfer fluid, and the flow meter is installed at the fluid inlet or return pipe (the final measurement results vary depending on the installation position of the flow meter). The flow meter emits a pulse signal proportional to the flow rate, while a pair of temperature sensors provide analog signals representing the temperature levels. The integrator collects signals from the flow and temperature sensors and calculates the heat obtained by the heat exchange system using the accumulation formula.
