Differential pressure devices, flow switches, and pressure gauges

No matter whether liquid or gaseous media, aggressive or contaminated, hot or cold, high pressure or low pressure are involved, the Differential pressure devices from Dosch can be used under virtually any conditions and ensure continuous and reliable plant monitoring. We offer products for various applications: from detachable orifice plates for small and large diameters and venturi tubes for difficult conditions up to and including flexibly usable averaging pitot tubes.

With their extensive longevity and operating times spanning many years, even in harsh industrial environments, our products set internationally recognized standards. The EARL flow switches are equipped as required, e.g., as pendulum devices for monitoring the flow of fluids or gases or as vane-operated switches for gases. Models are available for various installation situations and also for use under high pressures and high temperatures.

We are manufacturing U-tube-pressure gauges and inclined tube pressure gauges for low and extremely low pressures and differential pressures for almost 100 years. Our liquid pressure gauges are used as inexpensive and simple indicators in furnace construction and ventilation technology. Special designs with contacts are also available.
