The B Meters GSD8 Single-Jet Water Meter is the leading compact dry-dial mechanical water sub-meter designed for domestic tenant billing, residential apartments, and commercial office submetering. Featuring a 360° rotating register, high sensitivity, and full WRAS and MID R100 approval, the GSD8 is pre-equipped for non-magnetic inductive clip-on AMR communication modules (Pulse, M-Bus, Wireless M-Bus, and LoRaWAN).
Key Engineering Highlights:
- WRAS Approved & MID Certified: Fully approved for potable drinking water installations in the UK and certified to MID 2014/32/EU (R100-H / R50-V).
- Super-Dry Dial Mechanism: Dry dial totalizer with magnetic transmission guarantees that the gears remain clean, scale-free, and legible in all water qualities.
- Anti-Magnetic Fraud Protection: Equipped with internal magnetic shielding to prevent external tampering or magnetic deceleration.
- Retrofittable IWM AMR Modules: Inductive non-magnetic target disc supports clip-on IWM-PL3 (Pulse), IWM-MB3 (M-Bus), and IWM-LR3 (LoRaWAN) modules without unsealing the meter.
- 360° Rotating Counter: Allows effortless reading and cable routing whether installed horizontally or vertically.
