Water and wastewater plants rely on accurate flow, level and pressure measurement to dose chemicals correctly, protect pumps and report regulatory data. WELK Meters supplies electromagnetic flow meters, ultrasonic level meters, submersible level transmitters and pressure transmitters that are proven in Chinese municipal water projects — including rural water supply stations and wastewater plant upgrades on our project record.
Typical Measurement Challenges
Raw water and sludge lines abrade and coat sensors. Open channels and deep wells make level measurement awkward. Remote pump stations are unmanned, so instruments must report back over telemetry. And utilities need billing-grade flow accuracy on both intake and discharge.
Which WELK Instruments Fit
- Electromagnetic flow meters (WKLD series) — DN10 to DN3000, with PTFE or rubber liners and corrosion-resistant electrodes, for raw water, treated water and sludge. Accuracy up to ±0.3% of reading. Integral, remote and submersible-remote versions are available for flow chambers and valve pits.
- Ultrasonic level meters — non-contact level measurement for sumps, channels and chemical tanks, with integrated and split versions covering ranges from 3 m up to 70 m.
- Submersible hydrostatic level transmitters — 316L stainless steel probes for wells, reservoirs and wet wells, with anti-corrosion versions for aggressive media.
- Pressure transmitters — such as the TY812 2088-type for pump discharge monitoring and network pressure points.
- Multi-parameter water quality monitoring — online analyzers and integrated monitoring stations, as deployed in our municipal pipeline projects.
- Wireless telemetry instruments — NB-IoT pressure, level and flow devices for unmanned stations and district metering areas.
Project Experience
WELK Meters has equipped rural water supply stations for a provincial water group with PLC systems, online water quality analyzers, electromagnetic flow meters, pressure transmitters and ultrasonic level meters, and has supplied instrumentation for wastewater treatment plant upgrade projects. This domestic project record means our recommendations come from plants that are already running.
