ECBS008 Series Ultrasonic Water Meter

Description

The ECBS008 series ultrasonic water meter is a residential water meter developed based on the ultrasonic transit-time measurement principle. It is designed for measuring and monitoring the flow of water media, including domestic water supply, central air-conditioning system water, and equipment pipeline water.

The meter can effectively detect abnormal water usage conditions such as leakage, seepage, and pipe bursts, helping improve water management and system reliability.

Features

• Suitable for residential water supply, purified water, and direct drinking water metering.
• Pipe material options: PA66 and brass.
• Compact structural design with small installation footprint.
• Ultrasonic measurement technology with no mechanical wear, ensuring high reliability and long-term stability.
• Accuracy class: Class 2.
• Turndown ratio: R100 / R125 / R160 / R250 / R400.
• Temperature class: T30 / T50 / T70.
• Complies with GB/T778 and ISO4064 standards.
• Equipped with leakage and burst pipe alarm functions.
• Multiple communication interfaces available: RS485 and LoRaWAN.
