Page 4: Introduction
Operation of the AMF is based on the electromagnetic induction law of Faraday. The AMF is used to measure the volume flow of conductive fluids in a closed pipeline. Examples of applicable liquids are: water, salt water, sewage, pulps, slurry, acid, alkali, or any mixture of liquids and solids which have a specific minimum of electric conductivity. -

Page 7: Flow Measurement Principle
With the flowing fluid as the moving conductor and measuring- electrodes inside the flow-cell wall, the AMF detects an induced voltage which is proportional to the flow velocity. These velocity measurements are virtually independent of pressure, density, temperature and viscosity. Because of these operating principles, accurate measurements can be made of fluids containing solids such as ore slurry, and cellulose pulp. -
Page 8: Typical Applications
1.5 Typical Applications The AMF can be applied to a wide range of pipe flow measurements. Applicable liquids include pure liquids as well as mixtures of liquids and solids which have a minimum of electric conductivity. Examples are: • Water (hot water, chilled water, city water, sea water, waste water, etc.);... -

Page 11: Wiring
Never install the flowmeter or do the wiring with power supply on! Your AMF will require a power supply of either 85VAC-250VAC; 20VDC-36VDC. Opening the flowmeter enclosure you should see seven terminal blocks. Refer to Figure 2.2 Terminal Connectors for details regarding these terminals. - Page 12 SIG1 Signal 1 SGND Signal Ground SIG2 Signal 2 Shielded Exciting1 To Separate Model Sensor Shielded Exciting2 EXT + Exciting Current EXT - Exciting Current - VDIN Current Two lines 24V Spots ICOUT Analog Current Output Analog Current Output ICCOM Analog Current Output Ground POUT Flow Frequency (Pulse) Output...

Page 21: Power Up
2.4 Power Up The AMF does not have a power ON/OFF switch. When it is connected to power, it will start to run automatically. After the power is turned on, the flowmeter will run a self-diagnostic program, checking first the hardware and then the software integrity. -
Page 22: Quick Start Menu Navigation
Step 1: Power On Upon power up of the AMF you will be prompted with the flow measurement window. The flow measurement window in Figure 2.5 provides the user with real-time volume and velocity readings as well as a programmable alarm indicator and flow units. -
Page 23: Menu Windows & Details
3.0 Menu Windows & Details The AMF has 5 different levels of passwords which allow access to different menu windows and the ability to change their parameter settings. To enter the password, from the main screen, press the MENU + ENT buttons simultaneously. For access to all menus, enter the factor set password 07206, otherwise: Level 1 password (set by manufacturer as 00521): Allows users to read-only privileges of parameter settings. -
