We have passed ISO9001 quality management, ISO14001 environmental management and ISO45001 occupational health and safety management system certifications. All measuring instruments have national type approval certificates, and export products have CE and CE-MID certifications.

We have rich experience in overseas project delivery, supporting bulk export and complete set delivery, and can provide localized technical support and after-sales service for overseas projects.

We support full-process engineering services including instrument selection, scheme design, factory delivery, on-site installation guidance, commissioning and lifelong technical maintenance.

We provide one-stop supporting services including engineering scheme design, system integration, valve manifold matching and on-site scheme optimization to meet integrated project construction needs.

Yes. We provide full non-standard customization services for special calibers, special temperatures, special pressures, special anti-corrosion materials and installation methods according to customer on-site working conditions.

All devices support mainstream industrial signals including 4-20mA analog signal, RS485 digital signal and wireless remote transmission, which can be seamlessly connected with PLC, DCS and other industrial automatic control systems.

All explosion-proof models have obtained national explosion-proof certificates, comply with GB3836 explosion-proof standards, and are safe for chemical, oil & gas and other flammable and explosive hazardous working conditions.

We adopt multiple anti-corrosion and wear-resistant materials such as 316L stainless steel, PTFE and Hastelloy. Customized wear-resistant lining and anti-corrosion structures can effectively adapt to acidic, alkaline and abrasive fluid media.

Yes. All core products support customized high-temperature and high-pressure structures. Customized instruments can stably operate under ultra-high temperature and ultra-high pressure conditions, fully adapting to petrochemical and heavy industrial harsh scenarios.

We provide standard industrial pressure transmitters, high-temperature resistant types, corrosion-resistant types, explosion-proof types and differential pressure transmitters, which can adapt to pipeline pressure monitoring, tank pressure measurement and various extreme industrial working conditions.

Magnetic level gauges support on-site visual display with low cost; ultrasonic level meters are non-contact and suitable for conventional tanks; radar level transmitters adapt to high temperature, high pressure, dust, steam and complex harsh working conditions with higher measurement accuracy.

Electromagnetic flow meters are for conductive and corrosive liquids; vortex flow meters adapt to gas, steam and low-viscosity fluids; mass flow meters achieve high-precision measurement; differential pressure flow meters are suitable for high-temperature and high-pressure industrial working conditions. We provide one-to-one selection service.

We mainly manufacture and supply flow meters, level gauges and pressure transmitters. The full product line includes electromagnetic flow meters, vortex flow meters, mass flow meters, differential pressure flow meters, magnetic level indicators, radar level transmitters, ultrasonic level meters and industrial pressure transmitters.
