Ultra-low flow electromagnetic flowmeter
1. Overview
The ultra-low flow electromagnetic flowmeter is designed with the latest integrated
circuit, signal processing technology and sensor manufacturing process, and is specially used
for ultra-low diameter and small flow measurement. The product caliber range includes 3mm,
6mm, 8mm, 10mm, 15mm and 20mm, etc. It can be used in many fields such as chemical,
food, medical, environmental protection and so on.

4. Installation
Mini magmeter can be installed horizontally or vertically. It is recommended that the meter

is installed with the electrodes in or close to the horizontal plane to ensure that any passing air or
bubbles do not interfere with the measurement. If installing in a vertical pipe, it is highly
recommended that flow direction is upwards to guarantee that the pipe remains full at all times.
Ensure upstream and downstream straight pipe run requirements are met.
There are some general precautions for installation:
Avoid Areas Where Air Accumulates and
Open Pipe Outlets
The meter must remain full of liquid in order
to operate correctly. Avoid high points in
pipes where air may tend to accumulate and
vertical outlet legs.
Bypass Line for Easier Maintenance
It is good practice to install a bypass around a
meter to allow maintenance access without the
need to shut down the line. Ensure upstream and
downstream straight pipe run requirements are
met.
Avoid Strong Vibration
Piping should be securely fixed where there
are vibrations present. It is recommended
that the transmitter be mounted remotely in
these installations. For installations with
severe vibration, a flexible coupling is
recommended to prevent the transmission of
vibration through the pipe to the flow tube. In
all cases, the flow meter should be properly
supported upstream and downstream to
prevent undue stress being placed upon the
meter and flanges. NEVER
support a meter on it’s casing as this can cause
internal damage to the meter coils.
Avoid Negative Pressure Situations
Where the pipe system has a fall of over 5m after
a meter installation, it is advisable to install a vent
or vacuum breaker above the meter to prevent
damage to the meter liner.

Avoid Installing Upstream of a Pump
Avoid installing a mag flow meter on the
suction side of a pump as this may create
negative pressure in the line and damage the
meter lining. Wherever possible, always
install downstream of a pump.
Ensure Straight Pipe Run Requirements are met
when Reducing Pipe Diameter
When the pipe diameter is reduced to
accommodate a flow meter, it is recommended
that straight run pipe length requirements both
upstream and downstream are built into the
installation. It is further recommended that
reducers with a center cone angle no greater than
15° be used to ensure the consistency of the
liquid flow profile.
5. Wiring
There are 8 cables for wiring, which are depicted in Table 5.1 below.

6.1 The Operation of Display version
The keypad and display are shown in Fig. 6.1.
Notes: Hold ALT key and press ENTER key, the converter will display a login page and
password is required. Input proper password and press ENTER again. The system enters into the
setup mode. To exit from setup mode and return to measurement mode, hole ENTER key for a
couple of seconds. The system can automatically return to measurement mode if no key is pressed
for 3 minutes.

6.1.1 Running Modes
The meter has two running modes: Automatic Measurement Mode and Parameter Setting
Mode.
After power-on, the meter enters measurement mode automatically. Under this mode, the
meter fulfills all measurement functions, displays data and outputs signals.
There are four keys on the keypad. They can be used to enter the parameter setting mode
and change the meter’s configuration. The key operation does not affect the measurement and

DOWN: Scroll bottom line display;
UP: Scroll top line display;
ALT + ENTER: Enter into setting mode; ENTER:
Return to measurement mode.
6.1.2.2 Parameter Setting Mode
DOWN: Subtract one form the digit at the cursor;
UP: Add one on the digit at the cursor
ALT + DOWN: Cursor shifts left
ALT + UP: Cursor shifts right
ENTER: Enter/exit submenu;
ENTER: Return to measurement mode if held for 2 seconds at any location
Notes:
1 When using ALT key, hold ALT first and then press UP or DOWN.
2 Under setting mode, the meter returns to measurement mode automatically if no
key is pressed for 3 minutes.
3 When adjusting flow zero, UP or DOWN key can be used to change the sign (+/-).
4 When setting flow range, UP or DOWN key can be used to change flow unit.
6.1.3 Parameter Setting Operation
To setup the meter, changing to setting mode from measurement mode is the first step. Enter
ALT + ENTER key in measurement mode to pop a login page and password is required to enter. Input
authorized password and press ENTER again to confirm. The converter enters into setting mode if
the password is approved, otherwise it returns to measurement display.
6.1.3.1 Menu Items
Converter setting menu consists of 45 items. Many of them are set up by manufacturer before
shipping. It is not necessary to change them when applying. There are only a few of them to be set
by user according to the application. The menu items are listed in Table 6.1.
