5. RT 4 USER MANUAL The RT 4 is a battery powered rate indicator totalizer Each unit has a 6 digit LCD display screen that can be MENU to read in any engineering units The expected battery life under normal operating conditions IS about 4 years Quite often the RT 4 is used to spot check gun pump valve and overall system efficiencies When the RT 4 is used with the flow meter in this manner it is imperative to follow good flushing procedures for the flow meter The RT 4 will i perform as well as the flow meter After each use the flow meter must be thoroughly flushed and cleaned If the meter will be stored for any extended period of time we recommend that the meter be disassembled lubricated and reassembled Operating Modes There are three modes of operation for the RT 4 total mode flow rate mode and programming mode Selection for the flow rate and total mode can be done by touching the MODE area of the front panel Total Mode The maximum value totalized is 999999 i of units There is only one totalizer selection In order to reset the total the total mode must be selected The totalizer can not be accidentally reset in flow rate mode To reset push the reset button Flow Rate Mode The rate mode is based on a selectable gate time see Explanation of D RING Values By using a lower gate time the unit is more responsive This may result in lower resolution depending on the units selected and the flow meter Programming Mode The
6. e programmed to 10 When totalizing in cc s 1 10th place resolution is not possible There is one special BISTRO case for totalization in the RT 4 This is when you wish to read in 1 10th units but by dividing by 10 takes the average k factor below 25 For example You want to totalize in ounces with the JVM 20 This meter has an average k factor of 102 9 imp oz Into the Pr 4 address you would input 103 This would allow you to totalize in whole ounces only To read to the 1 10th place divide the average k factor by 10 which would give 10 to be inputted into Pr 4 Since this number is less than 25 we must p again by 10 and adjust the Pr 5 address to 10 Pr 4 would be 103 Pr 5 would be 10 and Pr 6 00000 0 and totalizing in ounces Pr 6 Totalizer decimal location Simply select the desired location by pressing the up or down button press entry and exit the programming mode AW Company 8809 Industrial Drive Franksville W 53126 P 262 884 9800 F 262 884 9810 Rev 1 Form RT4 doc 01 01 5 The following chart has a list of recommended programming variables in typical engineering units for various meters These are generic figures and are good for most applications For those who require a higher degree of accuracy compare the actual average k factor from the supplied calibration sheet to the calculated data in the chart by using the formula used in the Pr 1 examples above It also may be necessary to adjust the Pr 1 and Pr
7. ion sheet you would select the Es k factor in the desired engineering unit If that number is greater than 25 then input that whole number into the Pr 4 address For example You need to totalize in gallons with the JVM 20 This meter has an average k factor of 13164 3 maa Into the Pr 4 address you would input 13164 This would allow you to totalize in whole P only To totalize with 1 10th resolution simply divide the ave rane k factor by 10 You would input 316 into the Pr 4 address Pr 6 would have one decimal pe f 1 100th resolution is require then eee ie average K factor by 100 You would input 132 into the Pr 4 address and two decimal places into r 6 In both of these cases the imp unit was greater than 25 For numbers greater than 25 Pr 5 is left in default mode which is 1 You can proceed to the Pr 6 decimal location for totalizer variable When the average k factor is less than 25 the following steps should be followed For example The JVM 20 has an average k factor of 3 478 imp cc Since the Pr 4 address can only accept whole numbers the choice is limited to either 3 or 4 which in either case will create a lot of error However the Pr 4 address is linked to the Pr 5 address which allows for a multiplier of 10 to the Pr 4 value That will change the k factor number to 34 78 The address variable would be 35 not 34 for the Pr 4 which has a very slight error Once Pr 4 has been programmed then Pr 5 would b
8. s two decimal ae are Hides ten For example the HPM 15 with a Pr 1 value of 716 84 would have the following Pr 3 decimal location Pr 1 Pr 3 716 84 0000 00 The RT 4 would read a flow rate in cc min with two decimal points and it would take 716 84 seconds to update the display screen To improve on this situation simply follow this rule Movement of the Pr 1 decimal to the left causes a corresponding movement to the right in decimal location the of Pr 3 The reverse is true as well A better solution for the above example is Pr 1 Pr 3 7 16 000000 Now the RT 4 reads in cc min with no decimal location and the update time is 7 16 seconds Pr 2 There are five different settings Miriio gt Multiply measurement result by 1 Taena gt Multiply measurement result by 2 E gt Multiply measurement result by 4 o gt Multiply measurement result by 8 dei nn Multiply measurement result by 16 For silla The HPM 15 ku in cc min would have an update time of 7 16 seconds If this response is too slow the Pr 2 can be setto 1 and then Pr 1 can be adjusted to half its value which is 3 58 The Pr 2 could be set to 2 and the Pr 1 would be reduced further to 1 79 Pr 3 Decimal location determined when calculating Pr 1 Use DN or UP to move decimal point AW Company 38809 Industrial Drive Franksville W 53126 P 262 884 9800 F 262 884 9810 Rev 1 Form RT4 doc 01 01 Programming the Totalizer From the calibrat
