Introduction: The metal tube rotameter adopts the variable area measurement principle and is used to continuously measure the volume flow of liquid and gas in closed pipelines. Metal tube rotameter has It has the characteristics of firm and reliable structure, wide temperature range, high precision, low price, and can be used for flow measurement in various occasions. This series is an on-site intelligent indication type, with downward feed There are three installation modes: top out, left in and right out, and bottom in and side out. It can be widely used in the fields of national defense, chemical industry, petroleum, metallurgy, electric power, environmental protection, medicine and light industry. Body, gas flow measurement.
