Trusted worldwide for its fluid measurement instruments and sensors, George Fischer Signet is a leader in flow sensor insertion technology. We deliver advanced flow, pH, ORP, conductivity, resistivity, pressure, temperature and level measurement technologies which offer accuracy, dependability, ease-of-use and minimal maintenance.

Flow Sensors and Instruments

Georg Fischer Signet patented the world's first paddlewheel sensor over 40 years ago, establishing an industry standard still widely used today. Now our flow product line has grown to include a variety of materials and technologies all designed to suit a variety of process applications.

Installation Fittings

Georg Fischer Signet also offers a comprehensive portfolio of fittings designed specifically for use with various insertion sensors, thus making installation quick, easy and effective.  The fittings are available in a number of materials to ensure that we are able to offer a solution to meet all requirements. 

pH/ORP Sensors and Instruments

Georg Fischer Signet offers a comprehensive portfolio of pH and ORP measurement technologies that are suited for applications ranging from water & wastewater treatment to chemical processing. Whether you are looking for wet-tap assemblies or differential pH electrodes, GF Signet can provide you with the most effective solution for your needs.

Conductivity/Resistivity Sensors and Instruments

GF's growing line of conductivity and resistivity measurement solutions is fast becoming the premier choice in applications such as desalination, R.O., and water treatment. The rugged in-line and submersible electrode designs are a perfect complement to the popular ProPoint™ and ProcessPro® conductivity instruments.

Temperature Sensors and Instruments 

These sensors feature a rugged PVDF body that stands up to neutralisation tanks, plating lines and other harsh chemical processes. All can be submersed in process vessels or installed in-line, matched with the ProcessPro transmitters available in either panel mount or integral mount designs.

Pressure Sensors and Instruments

These sensors feature a rugged PVDF body that stands up to neutralisation tanks, plating lines and other harsh chemical processes. All can be submersed in process vessels or installed in-line, matched with the ProcessPro transmitters available in either panel mount or integral mount designs.

Level Sensors and Instruments

These sensors feature a rugged PVDF body that stands up to neutralisation tanks, plating lines and other harsh chemical processes. All can be submersed in process vessels or installed in-line, matched with the ProcessPro transmitters available in either panel mount or integral mount designs.
