M140H WIRELESS MBUS
Flush-mounted multi-jet meter for cold or warm water with electronic OMS compliant wMBus communicating register.
Product Overview
The M140H is a hybrid measuring capsule water meter with tamper-proof electronic sensing of the impeller and a fully electronic counter with integrated wMBus, OMS compliant, communication. The extensive range of cartridge interfaces and convertors allows for simple installation of the M140H, no matter which meter housing is found on site. Available with cartridge interface types TE1, IST, MOC, MOE and MET and convertors for A34, MB3, MUK, DM1, WE1, WGU and HT2 interfaces.
- wMBus to EN13757-4, OMS compliant
- AES-128 data encryption; Encryption Modes 5 and 7
- Direct inductive sensing of rotor movement
- Cold water up to 30°C, hot water up to 90°C
- Nominal flow rate Q3 2.5 m³/h
- Comprehensive portfolio of cartridges and convertors
Remote Reading Capabilities
Interoperable mobile or stationary remote reading of Honeywell's sub-metering product range. The register sends meter information such as meter index, historic values, and operating information periodically, which can be received by various mobile receivers or gateways.

Diagram Description: Dimensions A set of diagrams illustrates the physical dimensions (Width B, Diameter D, Centreline Height H₁, Capsule Above Thread H₂, Capsule Overall Height H₃) of the M140H meter for different interface types: MOC (Honeywell), MET (Metrona), TE1 (Techem), and IST (Ista). The width B is 77mm for MOC and 75mm for MET. The diameter D is 64mm for MOC. The centreline height H₁ is 80mm for MOC, 70mm for MET, and 76mm for TE1. The capsule above thread H₂ is 40mm for MOC and 50mm for MET. The capsule overall height H₃ is 65mm for MOC. Weights are 0.13 kg for MOC and 0.16 kg for MET.
Diagram Description: Typical Pressure Loss A line graph titled "TYPICAL PRESSURE LOSS" plots "Pressure loss in bar" on the Y-axis against "Flow rate in m³/h" on the X-axis. The graph shows a single line representing a flow rate of Q2.5, indicating that pressure loss increases with flow rate. At a flow rate of 0.1 m³/h, pressure loss is approximately 0.01 bar. At a flow rate of 1 m³/h, pressure loss is approximately 0.1 bar.
