HSIN8020 Analog Method Liquid Level Meter Calibrating Device
Description
HSIN Series analog liquid level gauge verification devices a standard device specially used for the traceability of liquid level instrument. It integrates the collection and processing of digital signal, analog signal and alarm signal. It is widely used in various calibration laboratories and measurement and testing institutes In the measurement of liquid level gauge, with the emergence of new products and technologies, the original verification method has some difficulties, such as low accuracy of standard instrument, inconvenient installation method and so on. Therefore, according to the requirements of 《verification regulation of liquid level gaugeJJG971-2019》, combined with the needs of users and the cutting-edge technology with the development of measurement, our company has successfully developed a set of multi-purpose, multi-functional, high-precision and automatic liquid level gauge verification device. The device is divided into simulation method and real standard method. The equipment meets the requirements of《 verification regulation of liquid level gaugeJJG971-2019》.
