About us
DN50-200mm
This water meter is used in pipe network trunk lines where flow fluctuations are relatively small. At the same time, small flows need to be taken into account. It can be used for measuring extremely large flows, such as behind water pumps, secondary water supply and other places.
Product Features
◆The application of hydraulic balance technology greatly improves the performance of low and high flow areas
◆The range ratio of the entire series of products is Q3/Q1=200
◆Optional copper-sealed counter with protection level IP68 to ensure that the counter surface does not fog up
◆The bearing system combined with a gemstone and tungsten steel shaft ensures the long-term stability and reliability of the product
◆The flow profile sensitivity level is U0/D0, water meter There is no need to install straight pipe sections before and after
. ◆The factory water meter is pre-installed with remote transmission magnets and can be upgraded online. Wired/wireless intelligent remote water meter
◆The factory water meter has a reserved pressure sensor installation boss, and the pressure sensor can be installed directly on the meter body
◆Sampling method: pulse sensor (positive and negative measurement), non-magnetic sensing, passive photoelectric direct reading
◆ Communication method: LoRa/LoRaWAN, NB-IOT, GPRS, 4G
◆Temperature grade: T50, T90 optional
Installation conditions
◆A filter needs to be installed at the water inlet end
