Flow Monitor & Flow Indicator DKG-1

Product catalog summary

Operation and Application: The DKG-1 flow monitor operates on a float measuring principle and is suitable for mechanical engineering, central lubrication, circulation lubrication, and transformers. It features universal orientation, high reliability, high switch accuracy, viscosity compensation, and adjustable switch points. It is available in EX-version according to ATEX directive and UL Recognized version.

Materials: The device is available in brass and stainless steel versions. Wetted parts include a spring made of 1.4571, a sight glass made of DURAN® 50, FKM gaskets (with optional NBR, EPDM), and hard ferrite magnets. Non-wetted parts consist of an anodized aluminum housing.

Measuring Ranges: The DKG-1 series offers various switch ranges for oil with a density of 0.9 kg/dm³, ranging from 0.1 to 90 l/min. The maximum operating pressure is 10 bar, with a pressure drop between 0.02 and 0.4 bar. The viscosity range is 30 cSt to 600 cSt, and the maximum temperature is 120°C (optional 160°C). Measuring accuracy is ±10% of full scale.

Operating Data: Different operating data apply for explosion-proof designs according to the ATEX directive and UL Recognized devices. Special scales and installation positions are available upon request.

Technical Drawing and Summary of Types: The document provides detailed dimensions and weights for various DKG-1 types, with overall dimensions and weights specified for each type.

Electrical Data: The device offers ingress protection of IP65 and IP67, with potential-free reed contacts that do not require a power supply. Various connector types and cable lengths are available upon request. The device complies with ATEX and UL standards, offering different configurations for change over and normally open contacts.

Electrical Connection: The device supports connectors in compliance with EN 175301-803, Form A, and M12x1, with cable options available for EX-version and UL Recognized switch contacts.
