Transit Time Ultrasonic Flow Meters

TFX-5000 Meter

DESCRIPTION

The TFX-5000 transit time ultrasonic flow meter measures
volumetric flow and heating/cooling energy rates in clean liquids as
well as those with small amounts of suspended solids or aeration,
such as surface water or raw sewage.

TFX-5000 flow and energy meters clamp onto the outside of pipes
and do not contact the internal liquid.

BENEFITS

By clamping onto the outside of pipes, the meters have inherent
advantages over other flow meter technologies, including:

• Reduced installation time and cost

• Non-invasive, non-contact measurement

• Continued operation during installation—no need to shut down
the process

• No pressure head loss

• No moving parts to maintain or replace

FEATURES

• Large, bi-directional flow measuring range

• Data log up to 8 records

• Modbus® RTU or BACnet® MS/TP over EIA-485; BACnet/IP,
EtherNet/IP, or Modbus TCP/IP; AquaCUE®/BEACON® connectivity

• Configure and troubleshoot over USB with SoloCUE

• Reynolds, ultrasonic speed and temperature compensation

• Large, easy-to-read graphical display

• Rugged, aluminum enclosure for a long service life in
harsh environments

OPERATION

Transit time flow meters measure the time difference between
the travel time of an ultrasound wave going with the fluid flow
and against the fluid flow. The time difference is used to calculate
the velocity of the fluid traveling in a closed-pipe system. The
transducers used in transit time measurements operate alternately
as transmitters and receivers. Transit time measurements are
bi-directional and are most effective for fluids that have low
concentrations of suspended solids and are sonically conductive.

APPLICATIONS

The TFX-5000 meter is available in a variety of configurations that
permit the user to select a meter with features suitable to meet
particular application requirements.

The TFX-5000 meter is available in two versions:

• A flow meter for water delivery, sewage, cooling water,
water-glycol mixtures, alcohols and chemicals

• A heating/cooling energy flow meter used in conjunction with
dual clamp-on RTDs for temperature measurement—ideal for
hydronic process and HVAC applications

TTM-DS-02221-EN-01 (August 2019)

An ultrasonic meter equipped with heat flow capabilities measures
the rate and quantity of heat delivered or removed from devices
such as heat exchangers. By measuring the volumetric flow rate of
the heat exchanger liquid, the temperature at the inlet pipe and
the temperature at the outlet pipe, the energy usage can
be calculated.

SoloCUE Flow Device Manager Software

The flow meter may be programmed through the keypad or with SoloCUE software. If the meter is ordered without a display/keypad, the
flow meter must be programmed with SoloCUE software. The software is used to configure, calibrate and communicate with TFX-5000
meters. Additionally, it has numerous troubleshooting tools to make diagnosing and correcting installation problems easier.
