The MA-920 is a small area flowmeter that measures and outputs minute flow rates of various liquids and gases. It is an advanced microflow meter that combines many years of manufacturing know-how of area flow meters with state-of-the-art electronics technology.
In the past, there were various difficulties in improving the accuracy of area flow meters for micro-flow rates, such as machining accuracy, friction acting on floats, and non-linear characteristics.
In the MA-920, these error factors are automatically corrected by a microprocessor equipped with calibration data, enabling high-precision measurement in the minute flow range. The 2-wire DC4 – 20mA wiring scheme makes it extremely easy to construct on site.
