Oasis Instrument Co., Ltd. is experienced in the design, manufacture, and commissioning of advanced water flow calibration systems. Our expertise enables us to create systems with pipe diameters ranging from DN15 to DN1200. These calibration systems are suitable for verifying a variety of flowmeter types, including velocity-type flowmeters, positive displacement flowmeters, Coriolis mass flowmeters, and differential pressure flowmeters. Our systems support real-time data acquisition, automatic data processing, automatic calibration certificate generation, and historical data retrieval.
