Overview
The document provides technical specifications and operational details for the DKME-1 Flow Monitor, which utilizes a float measuring principle. It is applicable in various fields such as mechanical engineering, central lubrication, circulation lubrication, and transformers. Key features include universal orientation, high reliability, high switch accuracy, a wide switch range, viscosity compensation, and adjustable switch points. The device is available in an EX-version compliant with the ATEX directive and a UL Recognized version.

Materials
The DKME-1 is available in brass and stainless steel versions. The brass version includes a nickel-plated brass body, while the stainless steel version uses 1.4571 grade steel for all wetted parts. Gaskets are made of FKM, with optional materials like NBR and EPDM available upon request.

Measuring Ranges
The flow monitor offers various switch ranges for oil with a density of 0.9 kg/dm³. The ranges vary from 1-20 l/min to 15-80 l/min, with corresponding gph and gpm values. The maximum operating pressure is 250 bar for the brass version and 300 bar for the stainless steel version. The device can handle viscosities from 30 cSt to 600 cSt and temperatures up to 120°C, with an optional increase to 160°C. Measuring accuracy is ±10% of the full scale.

Operating Data
Specific operating data apply for explosion-proof designs according to the ATEX directive and UL Recognized devices. Deviations in installation positions or operating conditions can affect measurement accuracy.
