F-2700 Series Insertion Vortex Flow Meters

          F-2700 Series Insertion Vortex Flow Meters deliver accurate mass flow measurement without the need for an external flow computer. They can be a great choice for steam and medium or high temperature hot water flow.

          In the right applications, insertion style vortex meters provide a very reliable and cost effective solution for mass flow measurement. They are often the best choice for flow measurement in larger diameter pipes where the expected process flow rates are within the operating range of the meter.

          The standard loop powered version of the vortex flow meter is equipped with the internal temperature compensation required for direct mass flow measurement of saturated steam. Each F-2700 Vortex Flow Meter is provided with a 4-20mA analog output for flow rate, a pulse output for totalization and a built-in user interface and display. The standard loop powered meter also includes HART. Optional versions are available with internal pressure compensation, multiple analog outputs and BACnet or MODBUS serial communications.
