Step 4. Fine Tuning

On the main unit, press M90 to enter into menu M90. There are three important numbers displayed on this window (refer to the figure below):

Transit-time ratio R (it is the % value on the upper right), signal strength S and signal quality Q. Their values shall fall into the right ranges in order t o justify the reading:

R: 97% ~ 103%

S: 600 ~ 990 Q: 60 ~ 99.

Strength+Quality

If these values are not in the above ranges, you need to verify the parameters you have entered

S=819,822 Q=88

System Normal in Step 2. If you believe your entries are correct and the three numbers are still off their ranges, you may need to check your installation. Here are some tips:

Moving transducers closer to or away from each other will increase or decrease the transit-time ratio R.

The sound speed information in menu M92 might also be useful for debugging. The displayed value should be close to the one you have entered in step 2.3

(M15). If you have entered fluid type in step 2.3 instead, and you do not know the fluid sound speed, you can find this information in the Appendix.

M92

Fluid Sound Vel

0.0000 f/s

If all the three parameters are good, your installation is done. You are ready to look at your measurement results on menu window M00. You should see an “R” in the low right corner of the main screen (M01~M05). This “R” indicates normal running Conditions.

Appendix

Transducer Installation Guide

A.1. Find the mounting site

(A) Pipe must be full of liquids at the measurement site.

(B) No heavy corrosion of deposition inside of the pipe.

(C) Must be a safe location.

(D) The straight run of the pipe must not be shorter than 15D as a general guideline, where D is the pipe diameter. Insufficient straight pipe length will degrade the accuracy of the results.

(E) The transducer mounting site should be 10D straight run upstream and

5D straight run downstream (see the following drawing.)

(F) If there are flow disturbing parts such as pumps, valves, etc. on the upstream, the straight pipe length should be increased. The disturbance strength of those flow conducting parts will be (low to high):

Single Bend -> Pipe Reduction / Enlargement -> Outflow Tee -> Same Plane

Multiple Bends -> Inflow Tee -> Out of Plane Multiple Bends -> Valve -> Pump

A.2.

Prepare the Pipe Surface

Clean the pipe surface where the transducers will be mounted. Remove moisture, rust, and dirt. Wire brush the surface if not smooth. Dry up the surface. A dry, clean surface will ensure a good acoustic bond between transducer and pipe.

A.3.

Prepare the Transducer

Clean the transducer surface. Keep the surface dry. Put lubricant grease on transducer surface as shown in the right figure. Do

not put more than necessary, especially for small pipe.

5

A.4. Install the Transducers

Notice: For horizontal pipe line, it is recommended to install the transducers on the side instead of on the top or bottom of the pipe. This is to avoid air

bubbles on the top and sediments on the bottom of the pipe

.

A.4.3. M1 type transducer:

First, mark the transducer installation location on the pipe surface according to the mounting spacing given in menu M25. You may need to make a paper template to help you accurately locate the transducer position, especially if you plan to use Z-method for the installation.

Then, connect the mounting fixture around the pipe. Leave the chain loose so you can slip the transducer underneath.

Apply a small amount of couplant in the prepared area of the pipe where transducers will be in contact.

Slip the transducer under the clamp fixture.

Tighten the screw. Do the same thing for the other transducer. Use the above figure as a reference.

If the pipe material is metal, you do not need the clamp fixture. The transducers will automatically attach to the pipe by magnetic force. Finally, connect the

Transducer cables to the main unit.

The drawback is that the user can't operate it by direct key-pressing

Basic Troubleshooting:

Menu 08 Codes:

Press the MENU 0 8 keys. If the letter “*R” displays on the screen, it indicates system normal.

If the letter “E” is read, it indicates that the current loop output is over ranged by 120%. This refers to the settings in Window No.57. Enter a larger value in

Window No.57, and the letter “E” will disappear. It can be ignored if no current loop output is used.

If the letter “Q” is read, it indicates that the frequency output is over ranged by

120%, and this refers to the settings in Window No.69. Increase the input value in Window No.69, and the letter “Q” will disappear. It can be ignored if no frequency output is used.

If the letter “H” is read, it indicates that the ultrasonic signal detected is poor.

If the letter “G” is read, it indicates that system is adjusting the signal gain prior to the measurement. Also, it means system normal. Only when the adjustment takes too long without stopping, can system be identified as abnormal.

Letter “I” indicates no signal is being detected. Check the transducer wiring connections are correct, the transducers are installed firmly, etc.

Letter “J” indicates a hardware defect exists. Normally, such defect is temporary; it could be eliminated by system reboot (power off and restart).

ERROR Quick DIAGNOSES Section:

The NCM-603 ultrasonic flow meter has adopted few errors, but sometimes problems may occur due to minor user error on the operation, wrong setting or terrible working environment. Therefore, it has an advanced self-diagnosis function to display the errors

(M08).

Hardware error diagnoses are normally performed upon each power on. Some errors can be detected during normal operation. Undetectable errors caused by incorrect settings and unsuitable measurement conditions can occur after the boot up. M08 helps to detect the errors and determine causes during good times; thus, problems can be solved in a timely manner according to the solutions listed in following tables.

Errors displayed in the NCM-603 are divided into two categories: Table 1 is for circuit hardware errors displayed during self-diagnosis upon boot up. Table 2 applies when errors are detected during operations.

A “F” may be displayed on the lower right corner of the screen after entering the measuring mode. When this occurs, it is necessary to restart the flow meter so the selfdiagnosis can once again try to detect and solve possible errors. If the error continues try to use the following tables to resolve the issue. If unable to resolve the error, please contact the manufacturer for assistance.

The problems and solutions are given in the following tables.

* Attach transducer to the pipe and tighten it securely. Apply a plenty of coupling compound.

* Remove any rust, scale, or loose paint from the pipe surface. Clean it well.

* Check the initial parameter settings.

* Remove the scale or change the scaled pipe section.

Normally, it is possible to change a measurement location. The instrument may run properly at a new site with less scale.

* Input correct liner in the flow meter.

* Solution refers to previous mentioned solutions.

* Solution refers to above-mentioned solutions.

* Check settings (refer to M56) and confirm if actual flow is too high.

* Check settings (refer to Window M66- M69) and confirm if the actual flow is too high.

* Reboot; resolve it by the method listed in Table 1, if error prosiest contact the manufacturer.

* Re-install transducers.

* Try different mounting technique using M24 (don’t forget to remount the transducers’ accordingly if currently on ‘Z’ try ‘V’. if on ‘V’ try then ‘N’…)

Once fluid is detected in the pipe, set 0 in M29.

Frequently ask Troubleshooting Questions:

Q: New pipe, high quality material, and all installation requirements are being met then “Why is there still no signal being detected?”

A: Check pipe parameter settings, installation method and wiring connections.

Confirm if the coupling compound is applied adequately, the pipe is full of liquid, transducer spacing agrees with the screen readings and the transducers are installed in right direction.

Q: Why is the flow rate still displayed as zero while there is fluid obviously inside the pipe and a symbol of “R” displayed on the screen?

A: Check to see if “Set Zero” was carried out with fluid flowing inside the pipe

(Refer to M42). If it is confirmed, recover the factory default in M43.

Q: Old pipe with heavy scale inside, no signal or poor signal detected: how can it be resolved?

A:

1 Check if the pipe is full of fluid. (If the pipe is not full or contain air

bubbles, the NCM-602 will not able to function properly.)

• 2 Try the Z method for transducer installation.

• 3 Carefully select good pipe section and fully clean it, apply a wide band of coupling compound on each transducer face (bottom) and re-install the transducers.

• 4 Slowly and slightly move each transducer with respect to each other around the installation point until the maximum signal is detected. Be careful that the new installation location is free of scale inside the pipe and that the pipe is concentric (not distorted) so that the sound waves do not bounce outside of the proposed area.

• 5 For pipe with thick scale inside or outside, clean the surface well removal all obstructions/grinned, if it is accessible from the inside.

(Note: Sometimes this method might not work and sound wave transmission is not possible because of the layer of scale between the transducers and pipe inner wall.)
