DK37 M8
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.
The DK37 M8 comes with vertical or horizontal process connections for NPT or G thread, flange adapters and many other connection options. To provide constant flow rates in case of variable inlet or outlet pressures, the VA meter is also available with flow regulators. It has approvals for hazardous areas and is suitable for use in Safety Instrumented Systems (SIS).
