Introduction:
The LiterMeter 4 is a programmable pump controller that controls up
to four dosing pumps (12VDC), individually and simultaneously. Ideally,
the pumps will be SpectraPure’s Peristaltic Dosing Pumps, but any small
12VDC pump can be used. A 12VDC/1A power supply is included and is
able to power all four SpectraPure pumps at once.
The LiterMeter 4 (LM4) may be laid flat on a shelf, set on its back, or Velcroed
to a wall or under a shelf. It can be orientated with the wires at the top or
at the bottom of the unit. When the orientation of the LM4 changes and
after a button is pressed, the display will flip so that it is readable, and the
5 buttons operate in the new orientation.
Functions are grouped in pages as “Settings”, “Calibrate”, “System”, and
“Inputs”. All parameters are updated and saved as soon as a button is
pressed. There is no need for an extra “do it” or “save it now” button.
A personal device (PD) such as a smartphone, tablet, PC or Mac may also
be used to control the LM4.
Settings:
Each pump can operate independently in one of several Modes: Off, On,
Daily, Dose, Once, Timer, or Delay.
Calibrate:
Easy-to-Follow Calibration Procedure using included 100 ml. graduated
cylinder.
System:
General settings including Inputs, Networks, and Calibrations.

Four Outputs for Pumps:
Each of four outputs (identified as A, B, C, and D) is connected to a
separate pump. Each pump has full access to all pages, functions, and
inputs. Pumps are connected to the LM4 with male-to-male 3-conductor
cables. SpectraPure can provide cables of various lengths from 3 to 25
feet long. They are heavy-duty and shielded, and are recommended for
proper operation.
Four Inputs for Level Sensors:
All four inputs (labeled as 1, 2, 3, and 4) can connect to a variety of float
switches and water detectors (sensors). Any input can be “assigned” to
control any or all pumps. Sensors are connected to the LM4 with male-
to-male 3-conductor cables. SpectraPure can provide cables of various
lengths from 3 to 25 feet long. They are heavy-duty and shielded, and are
recommended for proper operation.
Wireless Connectivity:
The LM4 has wireless (WiFi–2.4Ghz) connectivity to allow changing
parameters using a PD. After the LM4 connects to a router, it will use an
IP address assigned by the router to send interactive pages to the PD. If a
router is not available, a private network is avalible to provide PD-to-LM4
communication.
Firmware Updates:
Updated firmware (new features and bug fixes) can be downloaded from
our website to your PD and then used to update the firmware in the LM4.

Pairing the LM4 With Your Smart Phone or Personal
Device
Note: Components Needed for Pairing:
• Modem - Provides the Internet Connection
• Router - WiFi Transceiver (transmit/receive data packets)
• SpectraPure LM4 Liter Meter Pump Controller
• Personal Device: Desktop Computer, Laptop, Tablet or Smart Phone.
To allow for convenient local remote control of the LM4, and to capture
real local time, it will be necessary to create a WiFi interface connection
to a Personal Device (PD), which will provide programming and timing
control for the LM4.
Each LM4 has its own unique 4 digit SSID number, which is used to identify
the LM4 while pairing your personal device with and maintaining a local,
router based, WiFi network connection.
When the LM4 is powered on, the first screen will display the firmware
version and the network ID number unique to that LM4 (see example
below) SSID = LM4-6680).
The Following Steps will Guide you through
the Personal Device Pairing: Please note that
the Pairing Window interval is 6 minutes.
(Restart as needed.). Once powered on, the
LM4 will transmit a unique onboard WiFi
signal. Connecting your PD to this signal
will allow you to identify and store your
local router’s network name and SSID as the
connection bridge between your PD and
the specific LM4 you have paired.
Pairing your personal device with your LM4:
First, power on the LM4 and note the unique SSID,
displayed as ID: LM4-XXXX. (Ex: LM4-6680).
1. Next, open the WiFi Settings on your smart phone or other (personal
device) PD.
2. Select the LM4-SSID from the displayed WiFi network list. This will
connect your PD to the LM4’s unique WiFi address. The next steps will
enable the LM4 connection to your local router.
3. Now, open a web browser on your PD and type in the following URL
(IP address) 192.168.4.1

4. The Configure WiFi page should display on your PD’s screen
(see Fig. 1 desktop computer).
5. Click on or tap the blue Configure WiFi button. This will bring up the list
of local networks in your area.
6. From the WiFi network list, select your local router SSID (name) and
enter your WiFi password. (as seen in Fig. 2 laptop)
7. Once you have selected your network and entered your password,
click on or tap the blue Save button to record and Save your router’s
WiFi credentials into the LM4.
8. A confirmation screen will appear on your PD. (see Fig. 3). Important
Note: The router will assign an IP address to the LM4.
9. In WiFi Settings, be sure the local router is now selected. Use the
assigned IP address in your PD’s browser to control the LM4 from your
Personal Device. On the PD, you should now see a screen similar to Fig.
4. For more details on pairing the LM4, see “Quick Start: Pairing the LM4
with Your Phone”.
