Introduction

INTRODUCTION
WARNING
THIS EQUIPMENT INCLUDES SOME EXTERNAL NONMETALLIC PARTS. THE USER SHALL THEREFORE ENSURE THAT THE EQUIPMENT IS NOT INSTALLED IN A LOCATION WHERE IT MAY BE SUBJECTED TO EXTERNAL CONDITIONS SUCH AS HIGHPRESSURE STEAM WHICH MIGHT CAUSE A BUILDUP OF ELECTROSTATIC CHARGES ON NONCONDUCTING SURFACES. ADDITIONALLY, CLEANING OF THE EQUIPMENT SHOULD BE DONE ONLY WITH A DAMP CLOTH.
The TFX-5000 transit time 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 sewage. TFX-5000 ultrasonic flow and energy meters clamp onto the outside of pipes and do not contact the internal liquid.
The TFX-5000 meter is available in two versions:
• A flow meter for water delivery, sewage, cooling water, alcohols, chemical
• A heating/cooling energy flow meter used in conjunction with dual clamp-on RTDs for temperature measurement—ideal for hydronic process and HVAC applications
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.
Figure 1: Meter operation
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.
By applying a scaling factor, this heat flow measurement can be expressed in various units (Btu, Watts, Joules, Kilowatts and others).

Installation

INSTALLATION

Overview

Each of the installation steps that follow is explained in detail on page 11 through page 12 . The actual installation procedures differ slightly, depending on whether the transducers are fixed or adjustable.
If the transducers are fixed, you will:
1. Install the transducers.
2. Install the transmitter.
3. Wire the transmitter.
4. Program the meter. If the transducers are adjustable, you will:
1. Install the transmitter.
2. Wire the transmitter.
3. Set up the meter (select the optimum transmission mode, enter the site information, and enter the uid and pipe properties).
4. Install the transducers.
5. Complete the meter programming.

Installation Considerations

Mount the transmitter in a location:
• Where little vibration exists.
• That is protected from corrosive fluids.
• That is within the transmitters ambient temperature limits: –4…140° F (–20…60° C); relative humidity 0…85%, non-condensing; altitude 2000 m max.
• That is out of direct sunlight. Direct sunlight may increase transmitter temperature above the maximum limit.
• That protects the oleophobic vent from materials that may plug or seal the vent.

Equipment Required

• Screwdrivers, wide blade and tiny blade (for securing wires to the terminal blocks)
• User manual for the transducers
• Four #8 or M4 screws, if mounting the transmitter on a wall
• Stainless steel banding straps, if mounting the transmitter on a pipe

Wiring the Transducer

Wiring the Transmitter
Figure 24: Wiring connections
OTE: N Submersible transducer cables are larger diameter. Each cable requires a separate conduit hole. The standard yellow
cable and high temperature cables are small enough to use a single cable gland with a 2-hole grommet.
OTE: N Transducer cables have two wire-color combinations. For the blue and white combination, the blue wire is positive
(+) and the white wire is negative (–). For the red and black combination, the red wire is positive (+) and the black wire is negative (–). The transducer wires are labeled to indicate which pair is upstream or downstream.
1. Guide the transducer terminations through a conduit hole in the bottom of the enclosure.
2. Secure the transducer cable with the supplied conduit nut (if exible conduit was ordered with the transducer).
3. Install the ferrite to the cable: a. To open the ferrite, pull the fastener away from the
body of the ferrite.
b. Wrap the cable tightly around half of the ferrite and
place the cable into the groove.
c. Snap the ferrite shut.
4. The terminals within the transmitter are screw-down barrier terminals. Connect the wires at the corresponding screw terminals in the transmitter. Observe upstream and downstream orientation and wire polarity. See Figure 25.

Wiring the Transmitter
RS485 Output
The RS485 feature allows up to 126 transmitters to be placed on a single three-wire cable up to 4000 feet. All transmitters are assigned a unique numeric address that allows all of the transmitters on the cable network to be independently accessed. Either Modbus RTU or BACnet MS/TP protocol is used to interrogate the transmitters.
Flow rate and total can be monitored over the digital communications bus. When a USB programming cable is connected, the RS485 and frequency outputs are disabled.
