B39 VW-M

Description

No Moving Parts, high accuracy for years’ long.

B39 offering none moving components in flow sensor, avoid long term abrasion of mechanical parts which may result to inaccuracy measurement and failure of meter. Such design is also resistant to impurities, therefore no-inspections and maintenance cost-free.

AMR Ready (wired & wireless)

B39 VW series support multiple communication interfaces for both wired and wireless which suitable for any type of installation environment, e.g. M-Bus, RS485 (Modbus), Pulse, LoRaWAN (868MHz, 915MHz, 923MHz), NB, Sigfox, etc. With communication interfaces meter is easily integrated into Automatic Meter Reading (AMR), which provide reliable and scalable network to utility and bring down the meter reading cost for any application.

Long Duration Life Time

B39 VW series has no moving parts, presents IP68 on fully water proof, and its body is fabricated from durable cast iron material and cast steel material. This robust design makes the B39 VW maintenance-free and highly precise throughout its flexible 10 or 16 years battery life depends upon customers’ needs.
