Dynasonics TFX Specifications

Transit Time Flow Meters

TFX Ultra

DESCRIPTION

The TFX Ultra transit time meter measures clean liquids as well as those with small amounts of suspended solids or aeration such as surface water or sewage.

FEATURES

• Bi-directional flow measurement system

• Totalizer options include forward, reverse and net total

• Modbus RTU or BACnet MSTP over RS485; Ethernet connections including BACnet/IP, EtherNet/IP, and Modbus TCP/IP protocols

• Large, easy-to-read digital display

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

• Certified for hazardous area installation in North America and Europe

APPLICATIONS

TFX Ultra ultrasonic flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid. The technology has inherent advantages over alternate devices including: low-cost installation, no pressure head loss, no moving parts to maintain or replace, and a large, bi-directional measuring range that ensures reliable readings even at very low and high flow rates. The TFX Ultra 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 Ultra is available in two versions:

• A flow meter

• An energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement—ideal for retrofit, hydronic process and HVAC applications

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.

Temperature measurements, when used in conjunction with flow measurement, can yield energy usage readings in the form of heat flow. To find the net heat loss or gain, energy usage is calculated by multiplying the flow rate of the heat transfer fluid by the change of heat content in that fluid after it has done some kind of work.

An ultrasonic meter equipped with heat flow capabilities is designed to measure the rate and quantity of heat delivered or removed from devices such as heat exchangers. The instrument measures the volumetric flow rate of the heat exchanger liquid, the temperature at the inlet pipe and the temperature at the outlet pipe.

Rate of Heat Delivery = Q × (Tin – T

Where

Q = Volumetric ow rate Tin = Temperature at the inlet T

= Temperature at the outlet

out

C = Heat capacity ρ = Density of uid

By applying a scaling factor this heat flow measurement can be expressed in various units: Btu, Watts, Joules, Kilowatts, and others.

NETWORK OPTIONS

RS485 Network

All TFX Ultra meters come equipped with an RS485 and use a Modbus RTU command set (data can be returned in single-precision, doubleprecision, integer or oating point values) or an optional BACnet MSTP protocol. Up to 126 Ultra products can be run on a single daisy-chain network and be individually queried for ow rate, positive ow accumulator, negative ow accumulator, supply temperature, return temperature and signal strength. Flow accumulators can be cleared at discrete addresses or globally. The RS485 network is also compatible with EnergyLink, direct to Excel, application. (EnergyLink is compatible with Modbus RTU only.)

Ethernet 10/100 Base-T Network

If equipped with the optional Ethernet communications module, the TFX Ultra can be plugged into a LAN and queried for flow rate, positive flow accumulator, negative flow accumulator, supply temperature, return temperature and signal strength. The module contains Modbus TCP/IP, EtherNet/IP and BACnet/IP network compatibility.
