Hebei Ketai Instrument Co., Ltd.
About
Hebei Ketai Instrument Co., Ltd. (COTEC), founded in 2014 and based in Hengshui City, Hebei Province, China, is a high-tech enterprise producing industrial automation instrumentation for flow, pressure, temperature, and level measurement. Their KTLD electromagnetic flowmeter series covers the full range of process connections: compact (KTLD-TW), threaded (KTLD-TL), flanged (KTLD-TFP/TF3/TF), split-type (KTLD-F), and the KTLD-TFG scraper-electrode variant engineered for dirty and wastewater applications where electrode fouling degrades measurement accuracy. Volumetric flow measurement includes the LWGY-W clamp-type and LWGY-F flanged liquid turbine flowmeters for low-viscosity fluids, the LUGB vortex flowmeter family with anti-corrosion (LUGB-W), temperature-compensated (LUGB-FW/T), and flanged integral (LUGB-F) configurations, plus the LUZX swirl flowmeter for gases and steam. Pressure instrumentation spans the 3351 series differential and gauge pressure transmitters and the KTPG general-purpose and KTPX compact transmitter lines available in flanged, sanitary, and high-temperature configurations. The KTPT series handles level measurement in standard, compact, and water-application variants, while the KTT covers process temperature. All instruments connect to COTEC Cloud for remote monitoring and device management. The company holds ISO 9001, 14001, and 45001 certifications and provides multi-language support across six languages serving international markets in petroleum, natural gas, electric power, chemical, metallurgical, and building materials industries.
