Page 3: Introduction
Open the hinged top cover of the flow meter, the wiring ports of the P117 are shown in the diagram below: Turn on the power switch at the top of the meter, then you can proceed with using the flow meter. -
Page 4: Keypad Functions
Keypad functions The full keypad is pictured below, this will describe basic functionality of the keypad 0 – 9 keys input numbers, each word printed on the key also is a shortcut to that menu is also used as a decimal place button is also used as a backspace scrolls up and down menu numbers The enter a specifc menu:... -
Page 5: Select Installation Location
Select installation location Measurements cannot be made accurately if pipe is not filled, install transducers in a position that is filled with fluid, even after flow has stopped. Some below examples show areas that would be unsuitable for installation. Sediment Sediment accumulation at the transducer position may cause measurement errors. - Page 6 When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed to provide an accurate measurement. Use the following guidelines to select a proper installation site a) Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward...

Page 7: Transducer Mounting Methods
Transducer mounting methods Three transducer mounting methods are available, V method, Z method and N method. V method The V method is considered the standard method. It usually gives a more accurate reading and is used on pipe diameters ranging from 25mm to 400mm. It is also the most convenient to use and setup. V method –... -
Page 8: Parameters Setting
Parameters setting This guide will only tell you about the most basic menu’s – for a full description about each menu’s function please see the full manual Now that we have decided on a suitable installation location, and by now you should select the best mounting method for your pipe, we will need to program the pipes parameters into the flow meter, follow the below steps Pipe outer diameter (Menu 11) first press... - Page 9 To select your material first press then to scroll up and down selectable options, then again to confirm Hint: If your material is not one of those listed, please select ‘other’ here, then you will see if you go to menu 15 you can manually enter the pipe sound velocity which you can check back of the full manual for some other common material sound velocities, or you may be able to find your pipe material’s sound velocity with a web search.
- Page 10 Transducer mounting (Menu 24) Press shortcut, or press to enter menu 24 See page 7 (Transducer mounting methods) for more info on selecting the best mounting method, three mounting methods are available V – most common, can be used for 25mm to 400mm pipes Z - can be used if the signal is poor, best used on pipes over 100mm N - while uncommon to use this, it can be used on small pipes usually under 50mm Select the mounting method...

Page 11: Pipe Preparation
Pipe preparation This carries on from page 5 and 6 of selecting an installation location, so by now you should have already selected the ideal location to install the flow meter transducers. Remember to consider the possibility of sedimentation at the bottom of the pipe and the presence of an air pocket at the top of the pipe. -
Page 12: Transducer Installation And Fixing
Transducer installation and fixing Now the transducers can be installed onto the pipe, the frames themselves are magnetic so will stick straight onto magnetic pipes, or you can use pipe straps to attach them to other pipes such as PVC. The mounting conditions and positioning directly influences the flow value accuracy and system long-term operation reliability so it is important to mount the transducers correctly and accurately. - Page 13 For example, if your menu 25 says to space it at 80mm then put the transducers like this, 40mm from the end of each frame to make a total of 80mm between transducers Then the total frame together is ready to be mounted: Apply couplant to both transducer sensing surfaces, like in the below example: Silicone-based grease can used as an acoustic couplant, when selecting a grease ensure to select one that is rated not to “flow”...
- Page 14 Rotate the transducer mount which is spring loaded to ensure the transducer is firm up against the pipe. This rotary knob moves the transducer in and out within the frame for a snug fit. If you are installing the frames on a non-magnetic pipe, then you can use the pipe straps to attach the frames to the pipe, as shown below: Hint: in some situations, it might be easier for you to use only one frame, you could remove on transducer and place it into the other frame with it if you will always be using V method on small pipes...

Page 15: Connecting The Transducer Cables
Connecting the transducer cables Now connect the transducer cables as shown below – ensure you have upstream and downstream in the correct position – if wired backwards the signal and reading will be 0. Now the meter should begin reading, there are a few values you should check to ensure proper installation as per the next section. -
Page 16: Checking Signal Strength
Checking signal strength Check Signal strength (Menu 90) Press shortcut or press to enter menu 90 Signal strength indicates a detected strength of the signal both from upstream and downstream directions. The relevant signal strength is indicated by numbers from 00.0 – 99.9 00.0 represents no signal detected while 99.9 represents maximum signal strength. -
Page 17: Data Logging
Data logging Be aware when the capacity of the SD card is full, new data will overwrite old data automatically Though the files are small so it would take a while to fill the SD card. Data collection interval: Interval time is how often the unit will take a log, any interval setting from 1 to 60 seconds is acceptable. -
Page 18: To Retrieve Logged Data
To retrieve logged data Ensure the flow meter is turned off, remove the SD card from the flow meter (it is in the top panel) Using the included SD card reader, insert the SD card into the reader, then insert the card reader into a USB port on a Microsoft windows-based computer. - Page 19 Note the destination location that it will save to, or you can manually select a location, now press ‘Convert’ It will convert the file into an .xls file, open the newly converted file and you will see your logged data. 19 | P a g e...

Page 20: Basic Troubleshooting
Basic Troubleshooting If you are having problems acquiring or maintaining strong signal over 65 • Pipe parameters entered must be accurate; otherwise, the flowmeter will not work properly. • During the installation, apply enough coupling compounds to the transducer to ensure adequate contact with the pipe wall. -
Page 21: Frequently Asked Questions And Answers
Frequently asked Questions and Answers Question: New pipe, high quality material, and all installation requirements met: why still no signal detected? Answer: 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 the right direction.
