Company introduction

Main product

KeRui (weifang) Automation Equipment Co., Ltd.specializes in industrial automation instrument development, production and sales, technical services, and supportingequipment supply of specialized companies. The main products are flow meters, level meters, temperature meters,pressure meters, electrical meters, thermal intelligent meters, programmable controllers (PLC)DCS distributed control systems,and eight series of more than 1,000 specifications. Its products and technologies are widely used in electric power, metallurgy, petrochemicals, environmental protection, plastics, food, printing, tobacco,textile, dyeing, and other felds.

Valve Positioner: A valve positioner is a crucial control device that precisely regulates the position of control valves in industrial processes. It receives control signals from a controller and compares them with the actual valve position.

Flowmeter: A flowmeter is an instrument designed to measure the flow rate of liquids, gases, or steam within a pipeline or channel. 

Transmitter: A  transmitter is a device that senses a physical parameter, like pressure, temperature, or level, and converts it into a standardized output signal, usually 4 - 20 mA DC or digital signals.
