The Series TBS Insertion Turbine Flow Sensor comes in brass or stainless steel and has an available "hot-tap" model. The TBS has Series SDF fittings available to fit pipe sizes 3 to 40". Ruby bearings give the turbine a low coefficient of friction and long life. The low friction bearings also allow the Series TBS to handle a wide range for flow rates. Additional options for this meter include adapter fittings and valve assemblies. Series TBS is suitable for clean liquids and large pipe applications.
PRINCIPLE OF OPERATION
The Series TBS uses a turbine equipped with miniature magnets in the rotor blades to measure flow. Liquid flow rotates the turbine and a sensor detects the passage of the magnets resulting in a square wave output. The output signal can then be combined with the Series RTI for flow rate and total, and the Series BAT for a 4 to 20 mA signal conversion.
