Shanghai Guangda Meter Co., Ltd was founded in 1993, specializing in the production of the DB transmitter series and the GK intelligent electric actuator series.

The company uses Rosemount devices and Differential Pressure Sensor and Pressure Sensor for manufacturing process. Utilizing the sensor to conduct temperature test, fatigue test and hydrostatic test, making the transmitter have the function of temperature compensating, the company can eliminate the zero-drift and temperature drift of transmitter and thus enhances the stability of the produced transmitters. The DB transmitter series has quite a few advantages like high precision, good stability, strong versatility, small size, light weight and easy installation. It can be widely used in the testing and monitoring system of industries such as petroleum, chemical, electric power, metallurgy, textile, food and light industry to measure gage pressure, differential pressure and liquid level.

The GK intelligent electric actuator series utilizes the digital microprocessor and is a new generation electromechanical integration product with functions of remote-control operating, self-processing, and self-fault-diagnosing and the self-own servo system. It can substitute for imported products of the same category.
