Krohne Flow switch DW182

Flow switches are used for visual and/or electrical checking of liquid flow. The units are of rugged, glandless construction, and are available in several versions to suit a wide variety of industrial flow monitoring applications. These instruments, when ordered with the appropriate options, are certified for use in hazardous locations.

Limit switches

 Standard equipment for indicators G and A includes one limit switch (reed contact), contact rating 12 VA (type K1). A second limit switch (type K2) can be installed if required. Additionally, amplifier relays, type KV1 or KV2 (KV2 only in conjunction with indicator G), can be installed for higher contact ratings (up to 1200 VA).

Indicator G

All flow switches can be equipped with indicator G. Scale marks are from 1 to 10 to allow visual control of the flow rate. The switching point may be changed as and when required.

Indicator A

The DW 181, DW 182 and DW 183 flow switches up to meter size DN 200 (8") can be supplied with indicator A. The dial is marked in flow units (e.g. l/h, m3/h) to provide more accurate flow readings. The switching points are factory-set. With this indicator it is also possible to adjust the switching points under zero-flow conditions. The H3 high-temperature version is supplied without indicator.
