Transit Time Ultrasonic Flow Meters

TFX-500w Clamp-On Meter

DESCRIPTION

The TFX-500w transit time ultrasonic flow meter measures volumetric flow of clean water in pipes 10 in. or smaller. By clamping on the outside of the pipe, the ultrasonic meter installs without cutting or tapping the pipe.

FEATURES

• Clamp-on, non-invasive flow meter

• Bidirectional flow measurement system

• Measures flow rate, total and velocity of water flow

• Set up the meter through keypad interface or with SoloCUE® Flow Device Manager software

• Compact enclosure uses large, easy-to-read graphical display

• Modbus RTU or BACnet MS/TP over RS485 and BEACON®/AquaCUE® connectivity

BENEFITS

• Reduces installation costs, especially retrofits

◊ Installs without cutting into the pipe

◊ Eliminates flanges and pipe fittings

◊ Eliminates draining and air purging

• Eliminates ingress or leak points in pipes

• No moving parts to maintain

• No pressure head loss

APPLICATION

The TFX-500w meter is well suited for building automation, water distribution and wastewater collection in new and retrofit applications. In addition to having lower installation costs than an inline flow meter, the TFX-500w meter can be installed while the system continues to operate without interruption.

The TFX-500w meter is suitable for:

• Potable water

• Reclaimed water

• Chiller water

• Boiler feed

• Make-up water

• Condenser water

• Condensate

By connecting the TFX-500w meter to Badger Meter® AquaCUE or BEACON analytics cloud service, the meter becomes part of a system that tracks and monitors water use for commercial buildings, campuses and other large facilities.

OPERATION

Transit time flow meters use two transducers that function as both ultrasonic transmitters and receivers. The flow meters operate by alternately transmitting and receiving a frequency-modulated burst of sound energy between the two transducers. The burst is first transmitted in the direction of fluid flow and then against fluid flow. Since sound energy in a moving liquid is carried faster when it travels in the direction of fluid flow (downstream) than it does when it travels against fluid flow (upstream), a differential in the times of flight will occur. The sound’s time-of-flight is accurately measured in both directions and the difference in time-of-flight calculated.
