Overview
The DK37 M8 is a variable area (VA) flowmeter with electrical signal output and bargraph indication or mechanical indicator with two optional limit switches. The versatile all-metal measuring device is suitable for flow measurement of gases and liquids. Due to its sturdy design, the VA meter can be used at temperatures up to +200°C / +392°F or pressures up to 220 barg / 3190 psig. It is fitted with a needle valve as standard to accurately set the flow value.
