To ensure correct use of the meter, please readthis manual thoroughly. Safety Precautions:The following general safety precautions must be observed during all phases of installation,operation, service, and repair of this product. Failure to comply with these precautions or withspecific WARNINGS given elsewhere in this manual violates safety standards of design,manufacture, and intended use of the product. If this product is used in a manner notspecified in this manual, the protection provided by this product may be impaired.

The following symbols are used in this manual:! Standard Installation Hardware: For new construction or scheduledshutdown; once kit is installed, the flow meter can be installedor removed without system shutdown. Hot Tap Installation Hardware: For applications which require theaccess hole in the pipe to be drilled through the valve using awet tap drilling machine while the hydronic system ispressurized and operating.

NOTE: Installation hardware materials vary greatly based on pipematerial, pipe size and standard vs. Insertion flow meters may be installed in pipes which are under high pressure. Accidents withthese systems can cause serious injury or death.

Only persons experienced with high pressuresystems and related knowledge in the heating, cooling and fluid metering fields should attemptto install, adjust, or remove the flow meter. Please read all instructions before attempting toinsert or remove a flow meter.

ONICON will be happy to assist with technical recommendations and to provide guidance bytelephone or e-mail. On-site field engineering, installation and service is also available at additional cost. This clearance dimension will increase withlarge diameter pipes. The following diagrams should be used as a guide to the properlocation for installing the meter.

For best results, install the flow meter in a straight run of pipe, free of bends,tees, valves, transitions, and obstructions. Straight run requirements vary based on the nature of the upstream obstruction. See the table on the following page for guidelines in determining minimum upstream straight run requirements based on the nature of the obstruction. Note: Depending upon specific location details, more or less straight run may berequired to produce a satisfactory flow profile.!

How To Determine The Available Straight Pipe Diameters:For each application, locate the longest straight, unobstructed section of pipe no bends, tees, valves,other insertion probes, size transitions. When more than the minimum requiredstraight run is available, place the meter such that the excess straight run is upstream of themeter location. Refer to the chart above to determine how much straight run is required. To takeadvantage of this feature, the flow meter must be installed through an isolation valve.

Failure to do sonegates the ability to remove the meter without shutting down and draining the system. It willalso result in an excessive amount of stem protruding from the pipe.

Excessive stem lengthsunneccessarily expose the meter to incidental damage. First, it ensures that the proper hardware is used. Second, it simplifies order processingby standardizing the dimensions of the installation hardware. ONICON must have anaccurate measurement of the overall height of the installation hardware as measured fromthe outside wall of the pipe to the top of the valve in order to determine the correct stemlength when assembling the meter in our factory.

ONICON installation hardware kits consist of three separate component parts:Some type ofthreaded branchoutlet,Aninterconnectingclose nipple,And a full portisolation valve.

Different pipe materials require different branch outlets and may include additionalbushings to properly size the opening. Once the isolation valve is installed, the piping system can be flushed, filled andpressurized. The flow meter may now be inserted or removed by hand without having todrain the system.

Please read all instructions before proceeding with meter insertion. This eliminates the need to shut down and drain thepipe. In these cases, it is important to confirm that the installation hardware is suitable for usewith the flow meter provided by ONICON before it is installed.

Installation hardware generally consists of three separate component parts:Some type ofthreaded branchoutlet,Aninterconnectingclose nipple,And a full portisolation valve.! Tees of thistype will cause significant errors in the flow measurement.! ONICON records the stack height dimensionprovided by the customer at the time of order entry, and the information is used to size thestem.

The dimension is shown on the laminated insertion depth gage tag attached to themeter. Prior to installing the meter, confirm that the stack height recorded on the tag is close tothe actual stack height. This way ONICON can offer youcredit for your meter if you decide to exchange the meter for one with a different stemlength.

Returns may be subject to a restocking fee. Refer to the chart in Section 3. Grounding rings are used to suppress electrical interference at the installation location forelectromagnetic flow meters.

They are provided in pairs and are installed upstream anddownstream of the flow meter. The use of grounding rings significantly reduces electrical noiseand may be necessary for proper operation of flow meters installed in lined or non-conductivepipes.

Installation Instructions1. Install the rings upstream and downstream of the meter as shown above. Please note that the straight run requirements shown above are only for locating thegrounding rings with respect to the F- flow meter. The complete straight runrequirements for this meter are found in Section 3. Center each gasket on the grounding ring surface.

Do not allow the gasket to protrudeinto the flow stream. Use the torque specifications provided with the gaskets when tightening the flangebolts. Wire the two grounding rings together as shown and connect them to the flow meterearth wire. Connect this to a known good earth connection. See Section 3. When you are ready to refill the system, make sure that all lines are filled with water beforeinserting the meter into the flow stream. If the lines are not filled and this is a hot watersystem, some water may flash to steam and exceed the high temperature limit for the sensorhead assembly.

This flash over could also exceed the pressure ratings of the meter and theassembly could fail allowing steam and hot water to escape causing serious injury. Loosenclamping nut to facilitate installation.

Clamping nutKeep sensorhead fullywithdrawnduringinstallation. Thread hottap adaper onto ball valveand tighten asnecessary. Maintain a firmgrip on theenclosure whenopening valve. Crackvalve totest forleaks. Apply paste orTeflon tape asnecessary. Damage to this nut or the clampingring under the nut may prevent the assembly from properly holding the meter in the pipe.

Theclamping nut is not part of the sealing mechanism. When adjusting the meter position or removingit, be sure to hold the electronics enclosure firmly by hand before SLOWLY loosening thepositioning clamping nut. Failure to do this will allow the pressure to suddenly and rapidlyforce the meter from the pipe causing serious injury. The meter could also be damaged or breakapart causing a break in the water seal with the resultant loss of large amounts of water. Thehand effort required to hold the meter will be 0.

Begin by calculating the effort that will be required to hold the meter. Establish adequate footingfor this task, taking extra caution when working from a ladder or platform. Step 1:Maintain a firm gripon the enclosureto counteractthe effects of thepressure in the pipe. Step 2:Slowly open thevalve to the fullopen position. Step 5:Slowly push down onthe flow meter untilthe bottom of theenclosure rests on thetop of the depth gage.

Step 6:Carefully tightenthe clampingnut. Step 3:Use the end of the depth gage to pierce anyinsulation that may be present and rest thegage on the outside wall of the pipe.

When removing the flow meter, be sure to holdthe electronics enclosure firmly by hand before slowly loosening the positioning clampingnut. Failure to do this will allow the pressure in the pipe to suddenly and rapidly force themeter from the pipe causing serious injury.

The meter could also be damaged or break apartcausing a break in the water seal with the resultant loss of large amounts of water.

The handeffort required to hold the meter will be 0. Step 1:Slowly loosen the positionclamping nut whilemaintaining a firm grip on theenclosure to counteract theeffect of pressure in the pipe.

Step 2:Carefullywithdraw the flowmeter stem fromthe pipe until thesensor head isfully inside thehot tap adapter. Step 3:After the meter is completelywithdrawn, slowly close thevalve to isolate flow.

NOTE:The hot tapadapter willcontain a smallamount of water. Step 4:After the valve is completelyclosed, unscrew the hot tapadapter from the valve. For hotwater meters, partially unscrewthe adapter to vent pressurebefore fully removing the meter.

The main cause of damage to meters comes from accidentally closing the valve on the sensorhead. To avoid this, gently rotate the meter by twisting the electronics enclosure back and forth twist the stem, do not bend it while you slowly close the valve. If the valve touches any part ofthe meter, you will feel it as you are twisting the meter.

If the valve touches anything, it meansthe meter is not fully withdrawn. Usually a gentle twisting motion while withdrawing the meterwill clear any obstruction and permit the meter to withdraw completely. Use extracaution when working with hot water meters.

The most common causes of electronic failures are miswired connections during installation. When adding additional cable, record and carefully document any substitution of wire colors.

All electrical connections to the F- must be made through the 10ft cable provided with themeter.
