This product has a wide measuring range, high sensitivity, and good metering performance in low flow areas. The product is suitable for water metering in situations with large flow changes.
Product features
◆Full flow detection, high measurement accuracy, and overall performance is better than LXS rotary wing water meter
◆Built-in stainless steel filter design, the measuring components are protected to the greatest extent
◆The flow profile sensitivity level is U0/D0, and there is no straight pipe section requirement at the water inlet/outlet end of the water meter.
◆The high wear-resistant bearing system ensures the long-term stability and reliability of the product, and significantly increases the maximum flow rate of the product.
◆The watch case is treated with epoxy resin powder thermal spraying, and the entire watch complies with the requirements of the National Ministry of Health and European drinking water standards.
◆The counter adopts a copper seal counter, and the protection level reaches IP68, which effectively solves the fogging problem of the plastic cover counter.
◆The factory water meter has a reserved pressure sensor installation boss, and the pressure sensor can be installed directly on the meter body.
◆The factory water meter is pre-installed with remote transmission magnets. , can be upgraded online to a wired/wireless intelligent remote transmission water meter
◆DN40 is a threaded housing with the same length as the LXS rotor water meter.
◆Sampling method: pulse sensor (positive and negative measurement), non-magnetic sensing, passive photoelectric direct reading
◆Communication method: LoRa/LoRaWAN, NB-IOT, GPRS, 4G
◆According to the water environment, dry magnetic transmission and wet liquid seal can be selected
◆WS50/80/100 lengths are optional, the short version has the same length as the horizontal screw-wing water meter
◆Temperature level: T50, T90 optional
