The SW ITZER flow switches styles HR, PM, FM & GK-FM are robust piston / paddle operated instruments with very wide application capability manufactured with know-how from Honsberg, . These flow switches are for use with water, oil or other liquids. Style HR : Handles pressures upto 200 bar with several flow ranges in different line sizes suitable for W ater, Oil and other liquid application. Style HRM : Same as style HR flow switch, but with

●

PM additional 2½" (65mm) dial gauge added for direct reading of flow. Style FM / GK-FM : Ideal for low flow liquid applications. Style PM : An OEM version with adjustable setting. W hile brass version is used for non-aggressive media, the SS version is for aggressive liquids. HR & PM models have adjustable settings. Model FM / GK-FM is factory set for a fixed flow.

NOTES

HR/HRM . . MI / KI — In-Line Mounting

1.

Accuracy & Repeatability are one and the same for all blind switches. Settings will slightly shift with varying temperature.

2.

For oil application specify oil viscosity at operating temperature and set value. Suitable upto 180 CST oils only.

3.

Maximum flow setting range is referred to as FSR herein. The maximum flow value mentioned in the range tables are based on a nominal flow velocity of 2 meter/second. The instrument can handle higher flow if the process flow velocity is more than 2 metre/second. Maximum flow corresponds to range and not with reference to line size and it is the value that can through the instrument at 2 metre/second. A higher flow can through the instrument at higher flow velocities.

4.

In model HR, an additional switch head with a SPDT switch can be fixed at the bottom of the flow switch body, to facilitate two independent settings, such as Hi-Lo. DPDT action can be provided through Auxillary relay in a separate “GH” weatherproof housing.

5.

life of microswitch is 5 × 10 5 switching cycles for nominal load. To quench DC sparks, use a diode in parallel with inductance, ensuring polarity. A ‘R-C’ network is also recommended with ‘R’ value in Ohms equal to coil resistance and ‘C’ value in microfarads equal to holding current in Amps.

6.

For Model FM, max. flow specified herein corresponds to max. adjustable range value. It is lesser for lower range settings.

7.

Model HR is available both with microswitch and reed switch upto 32 mm line size. For sizes from 40 to 80 mm ONLY REED SW ITCH IS AVAILABLE. Customers are advised to opt for microswitch version where available as it has a higher current capacity. Reed switches are still available if customer prefers one-to-one replacement for earlier version.

8.

Model HRM is available from 8 to 25 mm NB only.
