Flow switch with pendulum
Series 107 weighted pendulum
Series 107hv with spring supported pendulum

The construction of these pendulum units has been developed over more than 30 years operational usage.

These reliable units are virtually maintenance free and are suited to the protection of high-value installations and machines. The units control the flow of liquids and gases in either horizontal or vertical pipes DN 15 to DN 5000 with pressure ranges PN 10 to PN 320.

Suitability

• Guards against pumps running dry
• Control of lubricating oil-, cooling water-; hot water
• Monitors cooling air- and hydraulic-circulation systems as well as the circulation of cooling agents in refrigeration plants.
• Boiler feed water control,
• Burst pipe control; overflow control; flow control on steam generating boilers and heat exchangers with type approved certificate.
• Control of the direction of flow in water supply net works,
• Fire alarm in offshore-sprinkler systems;
• Record of pipe breakage.

Models

Series 107 with weighted pendulum

When the medium enters in the direction of flow indicated by the arrow it moves the pendulum with target disc and weight, against the force of the weight, in the direction of flow. A permanent magnet is situated at the upper end of the lever which operates either one or two switch contacts, these are located adjacent to the system tube. Set point fixed in the range 0.1 to 0.35m/s.

Series 107hv with spring supported pendulum

Similar in principle to the 107 above but utilising a spring in place of a weight as the opposing force of the flow. This enables higher set points to be achieved, and by altering the spring tension the adjustment of the set point.
