  • Page 1 AMR100N Flow Rate Totaliser Instruction Manual...
  • Page 2 General Information This manual provides the necessary information for installation and operation of your flow instrument; for detailed information on any flowmeters or accessories supplied with your instrument please consult the relevant flowmeter product manual. This instrument should only be installed and maintained by persons familiar with local regulations, particularly those for workplace Health and Safety.

  • Page 4 1. Introduction 1.1 Product Overview The AMR100N Rate Totaliser is designed for computing and displaying volume and volumetric flowrate from a flowmeter with a pulse or frequency output. The instrument will display Flow Rate, Total and Accumulated Total in engineering units as programmed by the user. Simple flow chart programming with English prompts guides you through the configuration steps, greatly reducing the need to refer to the instruction manual.
  • Page 5 1.2 Specifications Glass reinforced Nylon (PA6) with a Polycarbonate lens, Santoprene Physical gasket, polyester decal. Enclosure provides an IP rating of IP65 Optional powder coated Aluminium enclosure Temperature Operating Temperature Range is -30 C ~ +80 C (-22 F ~ +176 Electrical Entries 3 entries - M16 x 1.5 Large dual line LCD with 6 characters 17mm high on top line, 8 characters...
  • Page 6 2. Operation 2.1 LCD Display Upon entering the programming mode the LCD will conduct a display test where all LCD segments are displayed for 3 seconds The resettable Total is always shown on the top line of the display. The accumulated total is shown on the bottom line of the display, indicated by the ACCUM TOTAL flag.

  • Page 8 However, if the new unit selection results in a value which cannot be displayed it will be set to zero. For example, if display units are changed from Litres to Millilitres and the total has a value of 1000L this will be zeroed, as there is not enough display digits for a value of 1,000,000mL. Pressing the Reset key and holding for a period of 3 seconds will reset the total to zero.
  • Page 9 2.3.4 Bidirectional Flow Measurement When using a standard single channel flowmeter with an AMR100 users will find that reverse flow in their pipe will produce the same flowmeter pulse signal as occurs during forward flow. This means that reverse flow will be counted by the AMR100 as if the flow were still travelling ‘forwards’.
  • Page 10 2.3.6 Display Backlight The display backlight will be automatically enabled upon connection of an external DC voltage supply in the range of 12-30V; the backlight is not available when operating on battery power. If it is required to reduce power consumption while operating on external DC power the backlight can be overridden by the user.
  • Page 11 2.3.10 Battery Power The instrument is powered by a Lithium Thionyl Chloride (Li/SOCl2) AA size battery which is non-rechargeable. When operating under average conditions the instrument is expected to have approximately 5 years of battery life; average conditions are considered to be a reed switch input from a ALPHADYNAMIC PUMPS SA flowmeter with no outputs used.
  • Page 12 3. Mechanical Installation 3.1 General Requirements Installation of this product should only be carried out by suitably qualified/trained personnel with an understanding of local regulations regarding electrical installations. It is recommended that the instrument is installed in a location where it is shielded from extreme varying weather conditions, and from chances of physical impact.
  • Page 13 3.5 Panel Mounting Mounting of the instrument in a panel requires a 95mm x 76mm (3.75” x 3.0”) rectangular hole to be cut in the panel – panels thicker than 3.2mm (1/8”) should substitute longer screws. The enclosure gasket must be used to maintain weather protection when panel mounted. It is possible to maintain the IP65 rating for the outside of the panel with an accurately cut hole and a flat/smooth panel.
  • Page 14 4. Electrical Installation All wiring connections should be made with good quality shielded instrument cable; wiring between terminals which are inside the instrument enclosure, or between a flowmeter and an integrally mounted instrument may use non-shielded wire. Cable shields or drain wires should be connected to the instrument ground (GND) at the instrument end only –...

  • Page 16 4.2.3 Voltage Pulse Input (Paddle-wheel Meters) 4.2.4 Variable Reluctance Coil Input (Turbine Meters)
  • Page 17 4.2.5 Quadrature Pulse Input (Hall) Note: If negative flow is displayed during “forward flow” conditions, swap the wiring connections for signal 1 and signal 2 (Quad). 4.2.6 QS200 / QS100 – 2 Wire Pulse...

  • Page 19 4.3.3 Remote Switches External switches may be connected to the AMR100 display to allow remote access to button functions, or to allow use of heavy industrial push buttons in environments where the standard switches may break or wear. Momentary normally open (NO) switches MUST always be used.
  • Page 20 5. Programming Parameters 5.1 Enter the Programming Menu To enter the programming menu the user must simultaneously hold the Max/Min (up arrow) button and the Reset (down arrow) button for a period of 5 seconds. While the user is holding these buttons the LCD screen will display a countdown from 5 to 1.

  • Page 22 5.6 Input Signal Configuration The input signal can be configured according to the number of input channels; single channel, or quadrature. The default input type is “SINGLE” and is the correct input type for most flowmeters. If the AMR100 is to be used with a flowmeter with quadrature output – a 2 channel signal which typically has 4-wires –...
  • Page 23 5.7 Calibration Data The calibration data menu allows the user to enter up to 5 points of calibration data for their flow meter; if the AMR100 was purchased integrally mounted to a flow meter then the calibration data will be factory set. Upon entering the calibration data menu the user is able to enter up to 5 points of calibration, with each point of calibration requiring a frequency value and a K-factor.
  • Page 24 5.8 Digital Output The digital output function is configurable for either a pulse output according to totalised flow, or an alarm output according to flowrate. The pulse output can be configured for an unscaled pulse or a scaled pulse, and the alarm can be configured for notification of high flowrates, low flowrates, or a combination of both.
  • Page 25 5.8.3 Flow Alarm The Alarm output is enabled by selecting ‘ALARM’ from the digital output menu. The alarm output may be configured as a ‘High Alarm’ which will trigger in the event the flow rate exceeds the alarm set-point, a ‘Low Alarm’ which will trigger in the event the flow rate drops below the set-point, or a ‘High/Low Alarm’...
  • Page 26 The default value for the low frequency cut-off is 0.1Hz, and the parameter is adjustable from 0.1Hz up to 9.9Hz. It is not possible to enable a rate display for input frequencies below 0.1Hz. 5.9.3 Rate Calculation Pulses The purpose of the ‘Rate Calculation Pulses’ parameter is to determine the number of input pulses which are used in calculation of the flow rate;...
  • Page 27 6. Diagnostics 6.1 Diagnostic Options 6.1.1 Serial Number The serial number screen allows the user to see the serial number for their product. This number will also be shown on the physical label on the outside of the display enclosure. This number may be needed if you contact ALPHADYNAMIC PUMPS SA for technical assistance.

  • Page 29 6.3 Troubleshooting Steps 6.3.1 Total Not Counting If the total display on the AMR100 is not counting it will be necessary to determine if the cause of the fault is a flowmeter failure, failure of the AMR100 itself, or incorrect setup of the AMR100.
  • Page 30 6.3.3 Inaccurate Readings If the AMR100 display is showing inaccurate readings of flowrate or total volume the possible causes are; incorrect configuration settings in the AMR100, electrical noise, or a faulty flow meter. Please follow the below steps to troubleshoot this issue. Obtain the calibration certificate for your flowmeter, if you no longer have the calibration certificate for your flowmeter you will need to contact ALPHADYNAMIC PUMPS SA technical support or the ALPHADYNAMIC PUMPS SA distributor from...
  • Page 31 6.3.5 No Pulse Received at PLC or FMS If your AMR100 is correctly displaying a flowrate and total but you are not receiving a pulse signal at your PLC, fuel management system, or any other device with a frequency input, this may be due to a fault at either the AMR100, the external device, or incorrect/broken wiring.
