FLOMEC TM050-LP (01) PDF Document

Before using your FLOMEC TM050-LP, please be aware of the following:

Usage Limitations:

• 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.

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

Installation & Operation Safety:

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

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

Electronic Noise:

• 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.

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

Install your FLOMEC TM050-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:

• 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 connections, 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 on the housing 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, as this can damage the housing.

Before using, check the meter’s accuracy and verify its calibration with 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 TM050-LP maintains two totals and can display the flow rate.

Batch and Cumulative Totals:

• The meter has 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 for single use measurements.

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

• To reset the Batch Total, first press DISPLAY briefly until TOTAL 2 BATCH is shown. Then, hold the DISPLAY button for 3 seconds to reset the Batch Total to zero.

• When fluid is flowing, a small propeller icon is highlighted.

• When the Cumulative Total reaches 999,999, an X10 icon will be highlighted, meaning you must add one zero to the 6 digits shown. When the next rollover occurs, an X100 icon will be highlighted, meaning you must add two zeros.

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, and the factory set time base will be highlighted (M = minutes, H = hours, D = days).

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 the meter is installed and purged of air before calibration.

Field Calibration Procedures (Correction Factor Method):

1. To enter calibration mode, 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 can now enter correction values from -99.9% to +99.9%.

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, press both CALIBRATE and DISPLAY buttons simultaneously. CALEnd will be displayed, and the unit will return to normal operation without the FAC (factory calibration) icon.

4. The entered correction will be applied to all enabled units of measure.

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

If the display becomes dim, blank, or shows the “LobAtt” message, replace the two 3-volt lithium batteries. The batch and cumulative totals, as well as calibration settings, are retained when batteries are removed.

Battery Replacement Steps:

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 or use other brands.

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.

The 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.

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 FLOMEC TM050-LP features a pulse output cable that delivers raw pulses from the meter electronics to provide a digital signal to customer interfacing equipment. For each rotation of the turbine rotor, a specific number of pulses are transmitted.

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, connected between the White (PULSE) wire and a 5-30 VDC power source.
