The DK32 variable area flowmeter is now available with an electrical signal output: the new version DK32/ESK3x with 4…20mA/HART 7 communication can be used for continuous monitoring, logging or control of low flow applications with liquids and gases.
Being in the portfolio for over 60 years, the series is a true KROHNE classic for small flows, typically used in 4…12 mm / 1/8…1/2“ pipelines, with the local indication of current flow via the mechanical scale. It features a compact design, no need for straight inlet and outlet sections, and an adjusting valve for flow regulation. With available hazardous area approvals, typical DK32 areas of application include process or carrier gases, dosing of chemicals or additives, vessel inertisation, purging, monitoring of analyzer sample flow or seal gas/barrier fluids. While previously only MIN/MAX limit alarms were possible in these applications, the new version DK32/ESK3x can now transmit the current flow to a PCS via 4…20mA/HART 7.
