Product description

Ultrasonic remote water meter is composed of flow sensor and microprocessor, and adopts advanced ultrasonic measurement technology to measure the flow of water flowing through the pipeline. It can communicate with other devices through wireless or M-BUS interface to form a remote meter reading management system. The management department can overtake the data in the meter at any time to facilitate the management of user water consumption.

Performance characteristics

Using ultrasonic measurement technology.

Without any mechanical transmission parts, the starting flow is low, and it is not affected by bad water quality.

High measurement accuracy and good stability.

It can measure heat and cold quantity.

Installation method: horizontal or vertical.

Environmental level: Class B electromagnetic environment: E1

Temperature class: T30, T90

Accuracy Class: Class II

Maximum Permissible Error

Maximum Permissible Error: low zone (Q1≤Q< Q2) maximum permissible error is ±5%

When the water temperature is less than or equal to 30C, the maximum allowable error in the high zone (Q2≤Q≤Q4) is ±2%; when the water temperature is> 30C, the maximum allowable error in the high zone (Q2≤Q≤Q4) is ±3%
