What is OGM-DPS ?
OGM-DPS is an electronic system , integrated with wide range of pump system for refilling station, for con-
trolling fluid dispensers.
The system provides
To set the desire dispenser volume or value.
Able to record first 100 dispensed record in memory
For User, User-friendly dispensing operation.
Economic Control Module to reduce over dispense volume
Operating Instruction
1) Press L/P to select L = Liter , P = Price
2) Key-in the Volume or Value ( Press CLEAR for change the clear the digit)
3) Press START to start the pump for dispensing the fluid
4) Operation will be STOP, when the dispense reach the desired value on the
LCD screen
For Non Preset Dispensing
1) Press START, Pump will operate and Press STOP to end the Operation
2) Round-Up Function, During the operation
A. press 7 for Liter Rounding up
B. Press 0 for Price Rounding Up
Operating Principle of Digital preset module
OGM-DPS Digital preset module is the main power supply for the pump system. The computer board of the
module will receive the pulses from the Oval Gear Rotor to calculate the volume flow through the meter.
OGM-DPS computer board will calculate to show Price and Liter on the LCD Screen.
When reach the preset value or volume, OGM-DPS will stop the pump.
Operation Principle –OGM
Oval gear flow meters are categorized as positive displacement flow technology. When liquid flows through
this type of positive displacement flow meter, two oval geared rotors measure a constant volume per rota-
tion within a precisely machined measuring chamber. With each rotation, a constant volume of liquid is
measured. The rotation of the oval gears is sensed via magnets embedded within the rotors. These mag-
nets transmit a high resolution pulse output. The output signal can be process externally via a remote dis-
play controller or PLC or via a variety of output/display options available as accessories attached to the flow
meters.
The positive displacement flow technology allows for precise flow measurement of most clean liquids re-
gardless of the media conductivity. Other liquid properties also have a minimal effect on the performance of
this type of meter. Flow profile conditioning is not required as with alternative flow technology options mak-
ing oval gear installations simple to install in tight spaces and at an economical price.
