Ultrasonic water meter with integrated valve

Product catalog summary

Overview: The ADD GRUP smart water meter integrates ultrasonic technology and a water valve for advanced water management and leakage control. It maintains high accuracy over a 16-year lifespan and can be integrated into AMI systems for comprehensive utility solutions.

Features:

Ultrasonic Technology: Utilizes two ultrasonic transducers for accurate flow measurement without wear from impure water.
Non-revenue Water Reduction: Monitors consumption, controls leakage with a shut-off valve, and provides reliable billing to reduce non-revenue water.
Accuracy: Class 2 accuracy with no moving parts, capable of measuring low flows starting at 1 liter per hour.
Communication: Offers RF for WAN and Bluetooth for local interface.
Intelligent Alarms: Supports alarms for leakage, burst, dry, reverse flow, and tampering, with display indications.
Design: Durable composite case, IP68 protection, easy installation, and suitable for outdoor use.
Data Registering and Storage: Records hourly, daily, and monthly data with a storage capacity of at least 24 months.
Battery: Equipped with a lithium battery lasting up to 16 years.
Display: LCD with 8 digits for easy readability and WAN signal level indication.
Measurement: Dual temperature monitoring and configurable target volumes.
Integrated Shut-off Valve: Modulates flow, shuts off supply for unpaid bills or leaks, and allows remote management.

Technical Specifications:

Models: WMV15 and WMV20 with nominal diameters DN15 and DN20.
Flow Rates: Permanent flow rates range from 1.6 to 4 m3/h depending on the model.
Dynamic Range: Ranges from R250 to R1600.
Temperature and Pressure: Temperature class T50, storage temperature from -25 to +70°C, and maximum pressure of 1.6 MPa.
Installation: Can be installed horizontally or vertically.
Interfaces: Bluetooth and dual stack LoRaWAN + Wireless M-Bus, with optional SigFox and various frequency ranges.
Standards: Complies with ISO 4064 (OIML R49) and MID Directive (2014/32/EU).

Dimensions: Dimensions vary for models with brass pipes, with specific measurements for D15 and D20.
