ERGOMERA-125.ВW — Ultrasonic Water Meter

The ERGOMERA-125.ВW is an industrial mains-powered ultrasonic water meter designed for commercial and process metering of drinking water, industrial water, river water, seawater, wastewater, and other liquids in pressurised pipelines.

The instrument measures liquid volume and flow rate, supports the connection of pressure and temperature transmitters, and maintains measurement, alarm, event, and operator-intervention archives. It can perform measurements in one or two pipelines, monitor reverse flow, transmit data in near real time, and provide process alarm and control functions.

Mains power supply, cable runs of up to 500 metres, a wide selection of flow sensor designs, and extended communication interfaces make the ERGOMERA-125.ВW an effective solution for water utilities, pumping stations, industrial facilities, wastewater treatment plants, large process pipelines, and automated metering systems.

The meter is certified in accordance with the requirements of the Technical Regulation for Legally Regulated Measuring Instruments, approved by Resolution No. 163 of the Cabinet of Ministers of Ukraine dated 24 February 2016. It complies with DSTU EN ISO 4064.

Conformity assessment procedure: Modules B + D.

A manager will contact you to clarify the price, flow sensor design, and required configuration.

PURPOSE AND CHARACTERISTICS

Measured Media

The ERGOMERA-125.ВW can be used to meter:

• drinking water;

• industrial and process water;

• Mean time between failures of at least 120,000 hours.

Design Features

• Threaded flow sensors — DN20 to DN40.

• Flanged flow sensors — DN20 to DN1200.

• Flangeless flow sensors with welded connection pipes.

• Full-bore measuring sections with minimal pressure loss.

• Type V2 insertion ultrasonic transducers for pipelines from DN250 to DN3200.

• Type V2-RShVS lock-chamber transducers that can be installed and serviced under pressure.

• Lock-chamber sensor maintenance without draining the pipeline.

• Optional clamp-on ultrasonic sensors.

• Single-channel or dual-channel versions.

• Separate installation of the calculator and flow transducers.

• Horizontal or vertical flow sensor installation according to project requirements.

• Flow transducer versions with ingress protection up to IP68.

The instrument consists of a measuring calculator, one or two ultrasonic flow measurement channels, and, depending on the selected configuration, temperature transmitters, pressure transmitters, analogue and digital signal modules, and data communication equipment.

Why Choose the ERGOMERA-125.ВW

The ERGOMERA-125.ВW is an industrial water meter developed and manufactured in Ukraine for complex commercial and process metering systems. It combines the accuracy of ultrasonic measurement, support for large pipeline diameters, extended analogue and digital interfaces, long cable runs, and readiness for integration into modern automation systems.

Unlike the autonomous ERGOMERA-125.ВА the ERGOMERA-125.ВW is intended primarily for facilities with an available mains power supply, continuous data exchange, a large number of monitored parameters, and the need to transmit information in near real time.
