PRECISION METERS
Precision Meters supplies ultrasonic water meters for accurate measurement of cold and hot water consumption in households, apartment buildings and commercial premises. The range includes 15mm to 50mm meters and uses static water flow measurement with no moving parts, helping support long-term measurement stability and reliability.
Each meter includes a 9-digit, multi-line LCD display showing total volume and instantaneous flow rate.

Note: No straight pipe sections required (U0D0). This allows for flexible installation in tight spaces.
The ultrasonic water meter range is ready for AMR and AMI applications. Communication options include:
Hourly, daily and monthly values of the measured parameters are stored in the meter’s internal memory. This supports easier monitoring and review of consumption patterns over time.
Integrated radio communication allows data reading via Wireless M-Bus telegram using 433 MHz or 868 MHz OMS T1 mode, LoRaWAN or NB-IoT.
The meter can register important usage and operating data, including:
The LCD display includes indicators and alarms for:
The Class C ultrasonic water meter range covers 15mm, 20mm, 25mm, 32mm, 40mm and 50mm meter sizes. The 15mm to 25mm meters include overload flow rates from 2 m³/h to 5 m³/h, while the 32mm to 50mm meters include overload flow rates from 7.2 m³/h to 24 m³/h.
Class D performance specifications are available for the 15mm, 20mm and 25mm ultrasonic water meter sizes.
