LOOP-POWERED FLOW RATE INDICATORS & TOTALIZERS

Menu Title	Description	Function
	Display Rate	Sets Rate as the default display
	Display Total	Sets Total as the default display
	Reset Total	Resets Total
	Calibrate	Calibrates for linear or square root input
	Low-Flow	Any input Cutoff below this number will display zero and not add to the total.
	Filter	Display unsteady inputs with stability
	Time Base	Seconds, Minutes, or Hours
	Totalizer Conversion Factor	Number multiplied by the rate to compute total. May be any number between .00001 and 59999
	Total Decimal Point	Independent of Rate decimal point.
	Pulse Output	Can be programmed to produce 1 pulse output per any accumulated total between 1 and 999
	Display	Select rate only, total only, or auto toggle between rate and total

Non-Volatile Memory

All programming and total values are stored in non-volatile memory. This means that the total will remain in memory for a minimum of ten years even if power is removed from the unit. Unlike some brands, these
totalizers do NOT require a battery so you don’t need to worry about losing valuable information when power is lost.


Totalizes All the Time

No need to worry about missing some counts. These totalizers will continue to count and totalize even while in the calibration or setup mode. So if you need to change the cutoff value and you can’t stop the flow, go right ahead, the meter will still totalize in the background.


Alternating Rate/Total Display

These totalizers can be programmed so the display automatically changes between displaying rate and total every 10 seconds. This feature is particularly useful if the meters are mounted inside a NEMA 4X or an explosion-proof enclosure.


Lockout and Menu-Title Disabling

The ability to modify programming values can be restricted by installing the lockout jumper on JP1.
When installed the Lockout Jumper disables the user’s ability to program the following functions:,,,,,, and .

In addition the following menu titles can be toggled On/Off when the lockout jumper is installed:,, and.


Isolated Open Collector Pulse Output

This feature will produce one pulse output per a given number of counts (user select). For example, these meters can be programmed to produce one pulse for every 500 gallons totalized. This output can be sent to a PLC or a counter.


Square Root Extraction

The square root extraction feature displays flow rate by extracting the square root from a differential pressure transmitter signal. The user selectable low-flow cutoff feature gives a reading of zero when the flow rate drops below a user selectable set point.

• Displays Flow Rates
  
• User Selectable Low-Flow Cutoff
  
• Only 2 Calibration Points Required

Totalizer Conversion Factor

The totalizer conversion factor is a number which is multiplied by the rate to compute total. For example, if the rate display is gallons per hour and total is desired in liters, a factor of 3.785 should be used. If the rate display is gallons per hour and total is desired in gallons, a factor of 1 should be used.
