KLD-3000GD

This series of products implement the National Standard of the People's Republic of China GB/T778-2018 The standard for drinking cold water meters and hot water meters. The ultrasonic water meter is an ultra -low -power intelligent industrial water meter. It adopts time difference measurement technology, pulse technology, signal digital processing technology and error correction technology. No mechanical activity parts, no parameters need to be set, installed at any angle, it is not easy to damage, the maintenance volume is small, the built -in data storage function, and the remote data output function is transmitted to the monitoring room through the wireless network. Solving the problem of high starting flow of traditional mechanical water meters, no measurement of small traffic, remote real -time meter -to -meter -in -time meter.

Product Features

• Single channels, dual -channel.
• Anti -large water flow impact can run stably at the maximum water flow rate for a long time, suitable for fire water.
• The characteristics of high accuracy, low starting flow, small power consumption, good stability, wider range of volume ratio, long service life and other characteristics.
• It has a variety of output functions, which connects NB-LOT/4G/GPRS/GSM wireless transmission to form a monitoring system.
• The diameter tube design, no pressure loss, no mechanical rotation parts, reduce the energy loss of water pump power, and reduce the cost of water supply by enterprises.
• Add temperature sensor to measure heating (cold) pipelines to return water temperature, and monitor the heat (cold) amount in real -time monitoring, which can realize the measurement function of the heat (cold) amount.
• Use micro -power consumption technology to supply battery power (battery life 26 years and upload once a day. If the upload frequency is shortened, the battery life will be reduced accordingly).
• You can add the RS485 interface according to different needs of the user to achieve the remote metering function of different needs, which is convenient for centralized management. When the pipe network runs abnormally, actively report to the management network to run abnormal information.
