Flow switch for industrial control and safety

Benefit from Dosch flow switches: With a long service life in harsh industrial environments, our flow switches set internationally recognised standards. A flow switch, also known as flow monitor, reliably monitors the flow in pipework and impresses with its simple handling and uncomplicated installation and removal. Whether for high pressure, extreme temperatures of up to 300°C or special installation situations we offer the right solution for your industry.

For maximum precision, our flow monitors are equipped with potential-free switching contacts, including SPDT-type changeover switches (magnetic or microswitches), inductive slot initiators or magnetic proximity switches in accordance with the NAMUR standard.

We have different types of flow switches for example flow switches for pump or flow switches for water and fluids. Our portfolio includes pendulum flow switches for liquids and gases with higher flow velocities or vane flow switches for gas, flow monitors with pitot tube or diaphragm plate individually adapted to your requirements. All devices stand for the highest quality and reliability.

Flow monitoring with the right flow switch

Our flow monitors combine durability, resistance and maximum precision. Whether gas flow switches – also known as vane-operated switches for gases –, flow monitors with pitot tube or diaphragm plate and pendulum devices – we offer the right products for monitoring the flow of liquids and gases.

Our EARL flow monitors and flow switches below will give you an initial impression of which devices are suitable for your requirements. All models can be customised and are manufactured by hand with precision – not mass production, but quality that impresses. Our type 107 and 172 flow monitors also have SIL and ATEX approvals.

Dosch flow switches – Proven in numerous industries

Our flow switches are used worldwide in various industries and in general plant engineering. Whether in the chemical industry, in shipbuilding, in open-cast mining, in heating technology, on drilling platforms or in oil production – Dosch flow switches stand for durability and reliability. They are also indispensable components in fire protection systems for sprinkler and pump monitoring, tank farms and exhaust air systems.

Our flow switches have also proved particularly effective in water pipes and pipelines. One example of this is the Great Man Made River project in Libya, one of the largest irrigation systems in the world. Flow switches were supplied by Laaser (EARL), which was acquired by Dosch in 2003, when the system was first installed. As part of a system overhaul in 2018, the original devices were replaced by modern flow switches from Dosch – many of which were manufactured by the same experienced employees who worked for Laaser back then.
