Ultrasonic heat meter is used for measuring and displaying the caloric release/absorb by the hot/cold liquid passing through cold/heat exchange system. It is comprised by flow sensor, microprocessor and temperature sensor. Microprocessor will calculate the caloric after get the flow signal and water temperature of entrance and outlet.
* High accuracy and unaffected by the magnetic field thanks to ultrasonic time difference method
* Signal is undisturbed thanks to Straight-through sound wave channel
* Accuracy is uninfluenced after a certain period as measuring configuration will not be wear because of no moving parts
* Straight-through integrated structure made by forging technology
* Ultra low power consumption, automatic data rectifying
* No resistance to water flow, lowest pressure loss
* Alarm of low power voltage, temperature sensor short circuit and open circuit
* Suitable for measuring high impurity content water
* Horizontal and vertical installation is available
