Choose Your Water-management Option

Keep measurement and valve requirements separate. A communication option does not automatically add prepaid control.

Select the pipeline diameterThen compare the product options below.

DN / Q3 / L below refer to the printed P50 ultrasonic series table, not a separate size guarantee for every valve assembly.

Reading-only Ultrasonic Water Meter

Actual product design shown; match the selected assembly and specification.

When you need readings, not a shut-off valve

Reading-only Ultrasonic Water Meter

Use ultrasonic water measurement for service connections without adding a rotating measuring mechanism.

  • No moving measuring parts inside the flow path.
  • Review low-battery, sensor and over-range alarm functions for operation.
  • Choose a compatible M-BUS, RS485, LoRa or NB-IoT configuration rather than assuming every interface is included.

Pair the Meter with Your Reading or Billing System

Select the meter function first, then connect the matching data and control equipment.

01

Meter the Water

The ultrasonic sensor measures the water flow without a rotating measuring element.

02

Select the Interface

Use the selected wired or wireless option with compatible equipment.

03

Read or Manage Credit

Collect readings; add prepaid control only with the dedicated assembly and matching software.

M-BUS / RS485 / LoRa / NB-IoT are alternative communication configurations in the series. They are not all standard interfaces on every meter.

Before You Order

Frequently Asked
Questions

Product, installation and system questions for your project.

Discuss Your Requirements
How does this differ from a mechanical water meter?

An ultrasonic meter measures using the difference in acoustic transit time. It does not use a rotating measuring mechanism in the water path.

Is prepaid control included on every ultrasonic meter?

No. The manufacturer supplies a reading-only version and a dedicated prepaid version. Choose the valve-equipped product and compatible billing system when control is required.

Do all models support R400?

The series description mentions up to R400, while the printed technical table and pictured samples have their own values. Use the selected model data; do not treat the series maximum as the default for every meter.

Can a standard installation length be used for the prepaid version?

Not without checking the finished assembly. The valve body and electronics can change installation dimensions.

What should we send for a quotation?

Send DN, normal / peak flow, quantity, required reading interface, installation length and whether prepaid valve control is needed.
