Overview

Georg Fischer is proud of it’s long history of success with roots going back more than 200 years when Johann Conrad Fischer laid the foundation. What began 1802 with a small copper smelting plant and development works for new alloys, has since developed to the global industrial concern as we know it today.

Towards the end of 19th century, the company first began with producing the long-standing malleable cast iron fittings, thereby creating the basis of today’s division GF Piping Systems. This day, it has become established on the market as a leading supplier of piping systems for the safe and reliable transport of liquids and gases. Despite the constant change, innovational strength and customer orientation remain the defining values for GF Piping Systems up to today.

2540 Stainless Steel High Performance Paddlewheel Flow Sensor

The Signet 2540 Paddlewheel Flow Sensor offers the strength and corrosion resistance of stainless steel for liquid applications with low velocity measurements

2540 Hot-Tap sensor specifications and limitations depend on the lowest maximum rating of the components associated with the system. For example, if a ball valve in the system is rated at a maximum 100 psi @ 175 °F, you must limit the entire system’s maximum pressure/temperature rating to 100 psi @ 175 °F. All higher maximum specifications MUST yield to the component with the lowest maximum specification.
