SECTION 1.0INTRODUCTION

1.1 PURPOSE OF THISGUIDE

Thepurpose of thisguideisto provideinstallation proceduresand basic operating and

servicing instructionsfor theONICON Model D-1401 and D-1402 PortableMetering

System.

1.2 SYSTEM DESCRIPTION

The D-1401 and D-1402 PortableMetering Systemsare designed to measure theflow

rateof conductiveliquids in multiplepipe sizes. They can also beused to perform

flow profiling for analysis of flow measurement problems.

The D-1401 Portable Metering System includes a F-1100 singleturbineflow meter

and can beused to measure1.25 inch and larger pipe sizes.

The D-1402 PortableMetering System includesaF-1200 dual turbine flow meter and

can beused to measure2.5 inch and larger pipe sizes.

Theflow meter portion of thesystem istypically inserted into a filled and pressurized

pipeviaan existing oneinch minimum diameter full port ball valve. For pipesthat

can be easily drained before and after

measurement, the flow meter can be inserted

into aoneinch minimum diameter outlet that

can accept a one inch NPT male threaded

adaptor. For filled and pressurized pipes

without installed full port valves, wet

tapping installation hardwarekitsare

available from Onicon.

Thedisplay moduleincludesan LCD

display, control switchesand cable. A single

9-volt alkaline battery, located in the display

modulebattery compartment, powersthe

completesystem, including theflow meter.

SECTION 2.0SYSTEM OPERATION AND SET-UP

2.1 SYSTEM OPERATI ON

The D-1401 and D-1402 Display ModuleLCD display showstheflow rateasa

number representing thefrequency output signal, in Hertz, from theflow meter.

The D-1401 Display Moduleshowsthefrequency output signal of thesingle turbine

from theF-1100.

The D-1402 Display Moduleshowstheaveraged output from

both turbines. Thissystem also hasthecapability of

displaying theindividual output from thetop or bottom

turbineby using theselection switcheson theDisplay

Module.

Thisfrequency output isthen converted to gallonsper minute

for the pipe size being measured via the laminated

conversion chart included with the system.

Pleasecontact Onicon to obtain conversion factors for any

pipesizesnot listed on thechart, or if you requirea flow rate

unit of measureother than gallonsor liters.

2.2 I NTI AL SYSTEM SET-UP

1. Insert theflow meter into thepipeto be measured. (Seemanual section

entitled “Flow Meter Information” for specific information on installation

proceduresand recommended insertion depths.)

2. Plug theDisplay modulecableconnector into the connector on theflow meter

output cable.

3. Turn theDisplay modulepower switch to the “ON” position and verify that a

number appears on theLCD display.

D-1401 & D-1402 Portable Metering System Installation and Operation Guide • 03-17

2.3 BASIC FLOW MEASUREMENT

1. Turnthepower switch(left) to“ON” position.

2. Set themiddle switch to “AVG” and allow 45 secondsfor the flow meter

circuitry to stabilize.

3. Record theaveragereading in Hz on thedisplay and refer to the laminated

conversion chart to calculate the flow rate. Please note that the frequency

number displayed may vary rapidly (by asmuch as10-15%) asaresult of

theactual flow conditionsin thepipe.

4. Locatethepipesize being measured on thelaminated conversion chart and

determinethe“Z Factor” for gallonsper minute(or liters per minute) for

that pipe size.

5. Then multiply theZ factor by the averagereading in Hz from step 3 to

obtain theflow ratein gallonsper minute.

2.4 FLOW PROFILING MEASUREMENT

D-1401 / D-1402 Systems:

Significant information about thenatureof flow acrossthe entirepipediameter

can beobtained by taking flow measurementsat incremental insertion depths.

Depending on thepipesizeto be measured, determine an appropriate

measurement increment that will providetherequired information. (For

example: when measuring theflow profileof an 8-inch pipe, measurements

may bemadeat 1 inch incrementsto providethedesired profile.)

Withtheflow meter properly inserted in the pipe, loosen thehot tap adaptor

lock nut and push themeter into the pipeuntil the end of themeter touchesthe

far pipewall. Using thisasastarting point, pull themeter back out by the

desired increment of measurement and measure the flow rate. Repeat this

processuntil readings havebeen madeacross theentireinterior diameter of the

pipe.

In largepipeswheretheflow meter isnot long enough to touch thefar pipe

wall, measurements can be made using the near pipe wall as a starting point.

Push theflow meter into the pipejust until aflow reading is obtained on the

display. (For the

D-1402 systems, thetop turbineoutput can beobserved to seewhen it clears

the pipewall and beginsto spin.) Beginning at that point, start making

measurements at the desired incremental insertion depths.

D-1402 System Only:

D-1401 & D-1402 Portable Metering System Installation and Operation Guide • 03-17

When using aD-1402 system, theindividual top and bottom turbine

frequenciescan beobserved asareference to theamount of rotational swirl

that is present at each insertion depth measurement point.

To utilize this function, set themiddle switch to “SELECT”. The right switch

can then betoggled between “TOP” and “BOTTOM” to display the

individual turbinefrequencies.

A stable, uniform flow velocity at themeasurement depth will beindicated by

having the same or very close (+/- 10%) to thesamefrequency reading on both

thetop and bottom turbine.

A significant differencebetween thetop and bottom turbinefrequency

numbers will indicatethepresenceof flow turbulence andswirl at the

measurement depth. The top and bottom turbines rotatein oppositedirections.

Turbulenceand swirl will either increaseor decrease thespeed of rotation of

oneof theturbines and will havetheopposite effect on theother turbine.

2.5 SYSTEM STORAGE AND MAINTENANCE RECOMMENDATION

1. Alwaysstorethesystem in itscarrying case when not in use.

2. Beforelong-term storage of the system, blow all excess water from the flow

meter turbine assembly and wipe the flow meter stem assembly dry with a

clean cloth. Donot put any lubricantson the turbine assembly. Oil based

lubricants will damage the flow meter’ s o-ring seals.

3. If storing thesystem for long periods of time, removethe 9-volt battery from

the Display Module and store it separately.

4. Theflow meter’shot tap adapter should bepushed completely down over the

turbineassembly and locked so that theturbinesareprotected when moving

thesystem to anew location or when storing thesystem.

5. Theflow meter turbines, bearingsand shaftscan becleaned using a30 percent

whitevinegar to 70 percent tap water solution. An old toothbrush can beused

to lightly brush around thebearings. Rinsewith clean water and blow off

excess water before storing.

SECTION 3.0INSTALLATION, REMOVAL & ADJUSTMENT

CAUTION

Insertion Flow Metersmay often beinstalled in pipeswhich are under high

pressure. Accidentswith thesesystemscan causeseriousinjury or death. Only

personsexperienced with high pressure systemsand related knowledgein the

heating, cooling and fluid meteringfieldsshould attempt to install adjust or remove

the flow meter. Refer to the installation drawings before performing any work on

these meters.

3.1 SITE SELECTION

Theclearancerequired for installation istypically 30-36” from the pipewall to thenearest

obstruction above thevalveassembly. Thisclearance dimension will increasewith large

diameter pipes.

Theenvironment should befree of corrosive liquids/fumes, temperature extremes and heavy

vibration. The following diagramsshould beused asaguide to theproper location for installing

the meter.
