FLOMEC TM100-LP (01) PDF Document

Before using your FLOMEC TM100-LP, please note the following:

• Use TM Series meters with water and other chemicals compatible with wetted components.

• Do not use the meter for fuel or incompatible chemicals.

• This meter features a computer for local electronic display plus a pulse output cable.

• The computer display measures in gallons or litres.

• These meters are not legal for trade applications.

• TM Series meters are very sensitive to electric noise if operated within 1 to 2 inches of some electric motors or other sources of electronic noise.

Install your meter in-line either horizontally or vertically or at the end of the hose adjacent to the nozzle. Installation to metal connections is not recommended. Install as follows:

1. Plan to install the turbine with a minimum straight pipe length as follows:

• Upstream from the turbine, allow a minimum straight pipe length of 10 times the internal diameter of the turbine.

• Downstream from the turbine, allow a minimum straight pipe length of 5 times the internal diameter of the turbine.

2. For Spigot (Pipe) End, use only primer and solvents approved for PVC gluing.

For NPT Fittings, wrap all connections with 3 to 4 wraps of thread tape (optional to use pipe thread sealant). Make sure the tape does not intrude into the flow path.

3. Attach the meter with the arrow pointed in the direction of fluid flow.

4. For NPT Fittings – Hand tighten the meter at the housing ends. Do not use a wrench or similar tool to tighten. This can damage the housing.

WARNINGS:

• Compatibility of this product’s material and the process fluid and/or environment should be considered prior to putting into service.

• Product should never be operated outside its published specifications for temperature or pressure.

• Make sure flow and pressure have been eliminated from the process pipe prior to installing or removing the product.

• Always use appropriate thread sealant when connecting the product to process piping.

CAUTIONS:

• To protect against leakage, seal all pipe threads with an appropriate sealing compound. Make sure the sealing compound does not intrude into the flow path.

• If connecting to new male pipe threads, burrs and curls can adversely affect accuracy. Correct the problem prior to turbine installation.

• Installation near high electromagnetic fields and high current fields is not recommended and may result in inaccurate readings.

The output pulse through the cable is a raw pulse. For each rotation of the turbine rotor, a specific number of pulses are transmitted via the attached cable. Pulse amounts can vary depending on pipe/meter size, flowrate, fluid type, etc. The pulse cable White wire is signal and the Black wire is common (GND). Some interface devices may not have an internal pull-up resistor. Use a minimum 820 ohms resistor if necessary.

The typical pulses per gallon for the FLOMEC TM100-LP and other models are:

Before using, check the meter’s accuracy and verify calibration by following these steps:

1. Make sure there is no air in the system by starting the flow until it runs steadily. Then, stop or divert the flow using a valve or nozzle.

2. Meter an exact known volume into an accurate container. For best results, meter with one continuous full stream.

3. Check the volume against the display or recording equipment. If the amount metered is accurate, further calibration is not necessary. If not, refer to the Calibration Section for further instructions.

The computer maintains two totals: the Cumulative Total (TOTAL 1) which provides continuous measurement and cannot be manually reset, and the Batch Total (TOTAL 2 BATCH) which can be reset to measure flow during a single use.

• Switching Views: Press the DISPLAY button briefly to switch between TOTAL 1, TOTAL 2 BATCH, and FLOWRATE.

• Resetting Batch Total: Press DISPLAY briefly to display the TOTAL 2 BATCH. Hold the DISPLAY button for 3 seconds to reset the Batch Total to zero.

• Flow Indicator: When fluid is flowing through the meter, a small propeller icon is highlighted.

• Total Rollover: When the Cumulative Total reaches 999,999, an X10 icon will be highlighted, indicating a zero must be added to the 6 digits shown. On the next rollover, an X100 icon will be highlighted, indicating two zeros must be added.

• Flowrate Feature: To use this feature, press and release the DISPLAY button until the FLOWRATE icon appears. The factory set time base will be highlighted to the right of FLOWRATE (M = minutes, H = hours, D = days). The display will indicate the rate of flow.

All units are configured with a “factory” calibration, indicated with a FAC icon on the top line of the display. Both gallons (“GL”) and litres (“LT”) are available. To toggle between factory units (gallons, litres, imperial gallons, quarts, etc.), hold the CALIBRATE button and briefly press the DISPLAY button.

The “field” calibration may be set by the user and can be changed or modified at any time. Totals or flowrate derived from the field calibration are invoked when the FAC icon is no longer visible on the top line of the display.

To return to factory calibration (FAC) from field calibration, press and hold both CALIBRATE and DISPLAY buttons for about 3 seconds until FACCAL is displayed, then release the buttons. The unit will return to normal operation and the FAC icon will be visible.

To ensure accurate calibration and operation, you must meet the meter’s minimum flowrate requirements.

Use the Correction Factor Method for field calibration. For the most accurate results, dispense at a flowrate that best simulates your actual operating conditions. Avoid “dribbling” fluid or repeatedly starting and stopping the flow.

1. To calibrate, press and hold the CALIBRATE and DISPLAY buttons for about 3 seconds until you see FLdCAL. Release both buttons and you will see CF – 00.0. You are now in the field calibration mode and values from -99.9% to +99.9% can be entered.

2. The +/- position appears as an “underscore” for plus or a “hyphen” for minus. The DISPLAY button selects the position and the CALIBRATE button toggles this character.

3. Press the DISPLAY button to select the numeric positions. Press the CALIBRATE button to scroll from 0 to 9. Enter the percentage of change you want the display to correct. When satisfied with the value, press both CALIBRATE and DISPLAY buttons simultaneously. CALEnd will be displayed and the unit will go back to normal operation, without the FAC (factory calibration) icon.

4. All enabled units-of-measure remain visible and selectable – the entered correction will be applied to all enabled units.

5. To return to factory calibration (FAC), press and hold both CALIBRATE and DISPLAY buttons for about 3 seconds until FACCAL is displayed. Then release buttons. The unit will return to normal operation and the FAC icon will be visible.

The meter is virtually maintenance-free. However, it is important the rotor moves freely. Keep the meter clean and free of contaminants.

If the rotor does not turn freely, apply a penetrating lubricant on the rotor, shaft, and bearings. Remove any debris or deposits from the rotor using a soft brush or small probe. Be careful not to damage the turbine rotor or supports.

CAUTIONS:

• Blowing compressed air through the turbine assembly could damage the rotor.

• Do not allow liquids to dry inside the turbine.

• Handle the rotor carefully. Small scratches or nicks can affect accuracy.

The computer display is powered by two 3-volt lithium batteries. When the display becomes dim, blank, or the “LoBAtt” message appears, replace the batteries. The batch and cumulative totals and all calibrations are retained when batteries are removed.

1. Remove the four Phillips-head screws from the face of the meter and lift the faceplate from the turbine.

2. Remove the old batteries and clean any corrosion from the terminals.

3. Install new batteries. Make sure the positive post is in the correct position. Use only P/N 113520-1 Kit (includes two P/N 902004-2 Batteries). Do not mix old with new. Do not use other brands or technologies.

4. When the batteries are replaced, the faceplate will power ON. Check the display to ensure normal functions have resumed before assembling again.

5. Reseat batteries, if necessary, and position the faceplate on the turbine housing. To avoid moisture damage, make sure the seal is fully seated. Tighten the four screws on the faceplate.

WARNING: (Battery) – Avoid mechanical or electrical abuse. Batteries may explode or cause burns if disassembled, crushed, or exposed to fire or temperatures in excess of 212°F (100°C). Do not short circuit or install with incorrect polarity. DO NOT INCINERATE.
