Your Instrumentation Partner in China
WELK Meters is an industrial instrument manufacturer based in Baoding, Hebei Province, China, founded in 2015. From our own factory we develop, manufacture and calibrate pressure gauges, pressure and differential pressure transmitters, temperature sensors and transmitters, ultrasonic and radar level meters, electromagnetic and ultrasonic flow meters, and NB-IoT wireless telemetry devices. Because every instrument is engineered, assembled and tested in-house, we can supply standard models quickly, adapt measuring ranges, process connections and output signals to a customer’s specification, and accept OEM/ODM and private-label projects from small volumes. Our instruments operate in water and wastewater treatment plants, district heating networks, power stations, chemical plants, metallurgical works and paper mills across China and in export markets worldwide. Every inquiry is reviewed by an engineer — not a salesperson — and answered with a technical recommendation and quotation within 24 hours.
