FLOMEC TM200-N-LP (01) PDF Document

Please observe the following notices when using your FLOMEC TM200-N-LP meter:

• Use TM Series meters with water and other chemicals compatible with wetted components. Do not use to meter fuel or incompatible chemicals.

• 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.

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

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

You can install your FLOMEC TM200-N-LP 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. Follow these steps:

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 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. To protect against leakage, seal all pipe threads with an appropriate sealing compound. Ensure the sealing compound 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.

NOTE: Installation near high electromagnetic fields and high current fields is not recommended and may result in inaccurate readings. Also, if connecting to new male pipe threads, burrs and curls can adversely affect accuracy. Correct the problem prior to turbine installation.

The output pulse through the cable on your FLOMEC TM200-N-LP is a raw pulse. For each rotation of the turbine rotor, a specific number of pulses are transmitted via the attached cable. The pulse cable White wire is signal and the Black wire is common (GND). A Calibration Report with specific calibration information for the meter is also included for your reference.

NOTE: Some interface devices may not have an internal pull-up resistor. Use a minimum 820 ohms resistor if necessary between a 5-30 VDC V+ source and the White (PULSE) wire.

The typical pulses per gallon for the TM Series are as follows:

Before using your FLOMEC TM200-N-LP, check the meter’s accuracy and verify its 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 on your FLOMEC TM200-N-LP maintains two totals and can display the flowrate.

• Batch and Cumulative Totals: The computer maintains a Cumulative Total (TOTAL 1) which provides continuous measurement and cannot be manually reset, and a 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.

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

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

All units are configured with a “factory” calibration (indicated with FAC on the display). Both gallons (“GL”) and litres (“LT”) are available. To switch between these units, hold the CALIBRATE button and briefly press the DISPLAY button to toggle between them.

Your computer may have other units of measure programmed into it, such as IGL (imperial gallon), QT (quart), CF (cubic feet), CM (cubic meter), BL (42 gal. barrel), CC (cubic centimeter), or OZ (ounce). Holding CALIBRATE and momentarily pressing DISPLAY will toggle through all available factory set units.

Switching between different units will not corrupt the total’s contents. For example, if the meter totalizes 10.00 gallons in GL mode and you switch to LT mode, the display will read 37.85 litres.

For the most accurate results, dispense at a flowrate that best simulates your actual operating conditions. Avoid “dribbling” or repeatedly starting and stopping the flow. Ensure you meet the meter’s minimum flowrate requirement of 20 GPM (75 LPM) for the 2-inch model. The meter should be installed and purged of air before calibration.

Follow these steps for the Correction Factor Method:

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. Push 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, less 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 should return to normal operation and the FAC icon will be visible.

The FLOMEC TM200-N-LP meter is virtually maintenance-free. However, it is important that 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.

CAUTION:

• 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 batteries are removed or lose power, the batch and cumulative totals and the field and factory calibrations are retained. If the display becomes dim, blank, or the low battery message “LobAtt” appears, replace the batteries as follows:

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.

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.

CAUTION: Batteries should ONLY be replaced with P/N 113520-1 Kit (Includes two each P/N 902004-2 Batteries). Do not mix old with new. Do not use other brands or technologies.

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.
