DUG – a variable area device for the highest demands

03.04.2012

The flow meter / flow monitor DUG works according to the variable area principle. The usual conical measuring tube was replaced by a slot nozzle. This special construction enables the installation of a special compression spring, which exerts an additional force on the float.

The compression spring
The spring force counteracts the float movement and thus enables the DUG device to be installed regardless of the position.	DUG construction drawing with compression spring
The spring force reduces the increase in the float. This increases the scope of the measuring range with the same flow. The individual measuring range depends on the selected DUG model.
The DUG compression spring increases the restoring force of the float. This largely prevents the float from getting stuck in the guide tube when it is dirty (independence from dirt).

DUG features

Robust design: aluminum sleeve protects the sight glass
Compact design: overall length of 132 - 222 mm
Large measuring range: (depending on the measuring range)
Independent of position: spring returns the float to its starting position
Sight glass: high quality borosilicate glass
Compressive strength: operating pressure max. 10 bar
Temperature: 120 ° C (standard version), 160 ° C (high temperature version)
Explosion protection: Explosion-proof design according to ATEX available
Encapsulated float: Magnets (hard ferrite) not in contact with media

Areas of application for the DUG float

DUG is already used in all industries for flow measurement / flow monitoring. Here are some practical examples in the industries

Process industry:	Monitoring of the process water supply in the grinding circuit of wet grinding plants Measurement of the cooling water flow in coating systems, e.g. for PET bottles
Plant engineering and construction:	Monitoring of the cooling circuit in vacuum distillation Display of water flow in car washes, e.g. Washers for finely polished glass
Process technology:	Measurement of cooling water in the glass melt
Water treatment:	Measurement of deionized water in the feed to the dilution tank during boiler water conditioning in power plants
Energy generation:	Display of the specified volume flow for the glass coating for solar modules

DUG is also used in the mechanical engineering, chemical, pharmaceutical, medical technology and laser technology sectors.
