Products Description
1. Overview
The ultrasonic heat meter is a measuring instrument based on the principle of time difference of ultrasonic propagation for flow measurement and heat accumulation calculation. It mainly consists of ultrasonic transducers, measuring pipe sections, paired temperature sensors, and an accumulator (circuit board). By driving the ultrasonic transducers with the CPU on the circuit board, it measures the time difference of ultrasonic waves traveling upstream and downstream to determine the flow rate. Then, it measures the temperatures of the inlet and return pipes with temperature sensors and finally calculates the heat released over a period of time.
This product integrates a data transmission interface, supporting data upload through the Internet of Things (IoT) to form a remote meter reading management system. Management personnel can read the data from the meter at any time, facilitating the statistics and management of users' heat consumption.
2. Product Features
(1) Suitable for both hot and cold water.
(2) Self-diagnosis function: alarms for flow sensor faults, temperature sensor open or short circuits, measurement out of range, battery low voltage, etc.
(3) Utilizes our company's patented flow measurement method (patent granted) and intelligent data error correction technology, ensuring high measurement accuracy and stability.
（4）Accuracy level: Class 2
(5) Powered by an internal lithium battery, with ultra-low power consumption, it can be used for (6+1) years or more.
(6) Equipped with an optical interface, supporting handheld infrared meter reading tools for on-site reading.
(7) High-definition wide-temperature LCD display.
(8) Optional M-BUS, 485, or wireless communication interfaces.
(9) Optional built-in IoT communication module (4G or NB-IoT) to form an IoT meter.
(10) Selectable power supply methods:
1) Internal battery power supply (default)
2) M-BUS power supply
3) External power supply (DC 7.5～24V)
(11)Ultrasonic metering, no mechanical wear and tear, with excellent reliability, stability
