NEULOG DROP COUNTER LOGGER SENSOR GUIDE
NeuLog drop counter logger sensor
NUL-223
The NeuLog drop counter sensor can be used for any science experiment which
utilizes fluid drip rates, particularly in the fields of Chemistry and Biology.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using this guide.
The NeuLog drop counter sensor excels in the laboratory but can also be used in the
field for a number of experiments in various configurations. For example, titrations
become much more accurate as you can determine both the total number of drops
and the total volume which has passed through the drop counter sensor.
The drop counter sensor's measurement units are:
Drops: The number of times a drop of liquid passes through the drop
counter sensor.
Milliliters (mL): The SI unit of volume. The NeuLog drop counter sensor
calculates the rough volume of drops which pass through it.
Setting up the drop counter sensor:
There are a number of ways to set up the NeuLog drop counter sensor to give
accurate readings. The drop counter gate includes three threaded holes and a
threaded utility rod which can be attached to various lab equipment to offer many
different orientations.
The most important aspect while setting up the drop counter sensor is to ensure that
the drops of liquid are passing through the sensor correctly. As in the figure below,
you will want to orient the sensor so that drops pass through the infrared beam
transmitted between the ends of the drop counter sensor.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-223 Drop Counter Sensor
USB-200 USB Module
USB to mini USB cable (included with the USB-200 module)
Your drop counter sensor needs to be connected to a USB-200 module. The USB-200
module then connects to a computer via a USB to mini-USB cable. Please note that
you cannot plug the drop counter sensor directly into the computer.
The browser based application can be downloaded for free at www.NeuLog.com as
well as a full application user guide.
Choose "Downloads" on the main menu and then choose "Software and Application".
Procedure:
1. Install the NeuLog application.
2. Connect the USB-200 module to the PC or Mac.
3. Connect the drop counter sensor to the USB-200 module (they directly plug
together). Please note that no calibration is required for this sensor.
4. Open the NeuLog application by clicking on the shortcut on the screen.
5. Once a drop counter sensor module box appears on the left side of the screen
the probe has been automatically identified and you can begin experimentation.
6. If the drop counter sensor is not automatically identified then click the “Search
for sensors” icon to find the sensor.
7. Select the “On-line experiment” icon; this will open a graph below.
8. Click on the “Module setup” button located in the drop counter sensor module
box to change the sensor settings if need be.
9. Click on the "Experiment setup" button to change the experiment settings if need
be (experiment duration for example).
10. The drop counter sensor will give a live reading in the module box to the left of
the screen while plugged in.
11. To run an experiment and collect data click the “Run experiment” icon.
12. To end data collection early, click the “Stop experiment” icon.

Tablet, smart phone device
Materials needed:
NUL-223 Drop Counter Sensor
WIFI-201 WIFI Module
BAT-200 Battery Module
Your drop counter sensor needs to be connected to a WIFI-201 module. The WIFI-201
module will create a closed NeuLog WiFi network which will stream the NeuLog data
to a device of your choosing. Once your device is wirelessly connected to the NeuLog
network, you can run experiments and collect data through a browser of your
choosing.
Procedure:
1. Connect the drop counter sensor directly to the left side of a WIFI-201 (no wires
required).
2. Connect a BAT-200 module to the right side of the WIFI-201 module.
3. Although not required, we recommend plugging the BAT-200 to an outlet using a
USB to mini USB charger (such as a typical cell phone charger). The WIFI-201
module will run for 60-90 minutes (depending on the sensor) without being
plugged in.
4. The WIFI-201 can be powered directly using a mini to USB cord and plugging it
into your computer or a wall charger. Please note this function is only available
on WIFI-201 modules with the USB icon on the cover.
5. For further WIFI-201 instructions or the WIFI-201 quick start guide please visit:
www.NeuLog.com; Choose "Products" on the main menu,
then choose "WiFi Communication module".
6. The WIFI-201 indicator lights will flash; take no action until the LED to the far left
turns blue; this can take up to one minute.
7. Take your tablet or smart phone, go to the WiFi settings and select the NeuLog
network (NeuLog0184 for example) which matches the ID found on the back of
the WIFI-201 module (0184 for example).
8. Give your device about 20 seconds to connect to the WIFI-201.
9. Once the device is connected, go to your browser and type the website
wifi201.com into the URL bar, then wait for 30-60 seconds.
10. You will see a “Control mode” icon in the application, click on it.
11. The application will then load a new screen and begin to auto detect the
sensor(s); this can take a minute. (You can stop the search when the sensor is
found.)
12. If the application does not auto detect the sensor(s), select “Search for sensors”.
13. Once the sensor is found you will see a module box on the left side of the screen
for the drop counter sensor. In this box, real time data will be displayed.
14. Click on the “Module setup” button located on the drop counter sensor icon in
the module window to change the drop counter probe settings if need be.
15. Click on the “Experiment setup” icon to change the experiment settings if need
be (Experiment duration for example).
16. To run an experiment and collect data, click the “On-Line experiment” icon, then
click the "Run experiment" icon.
17. If you have a newer generation WIFI-201 (with the USB icon on the cover) this
can be used as a USB-200, meaning you can tether the probes directly to the
computer using the WIFI-201. To engage operation in this fashion, press 3 times
on the panel button. Repeating this operation will return the module to WiFi
mode.
Operation with NeuLog Graphic Display Module (viewer)
Materials needed:
NUL-223 Drop Counter Sensor
VIEW-101 Graphic Display Module
BAT-200 Battery Module
Procedure:
1. Connect the drop counter sensor to the left side of the viewer.
2. Connect the BAT-200 module to the right side of the viewer.
3. The VIEW-101 will auto detect the sensor and you will see it appear on the left
side of the screen.
4. Once the sensor appears it will be monitoring data in real time.
5. To run an experiment and collect data press the run icon (little green person).
Off-line experiments
(Off-line experiments are when you do not have a sensor connected directly to a
computer, tablet, smartphone, or NeuLog viewer).
Materials needed:
NUL-223 Drop Counter Sensor
BAT-200 Battery Module

NEULOG DROP COUNTER LOGGER SENSOR GUIDE

NEULOG DROP COUNTER LOGGER SENSOR GUIDE
Technical background:
The philosophy behind NeuLog’s plug and play technology is based on each sensor’s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (oC, oF, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in software in the logger can be
upgraded for free at any time using the provided firmware update.
The NeuLog drop counter sensor uses an infrared beam which passes between the
two endpoints of the sensor probe to count drops. As liquid passes through the
infrared beam, infrared light is scattered and not noticed by the infrared detector on
the opposing side.
Regardless of the liquid's opacity or color, the infrared light bends away from the
detector. Each time there is a break in the infrared beam, a drop is counted.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the drop counter sensor’s body and probe.
After use, gently wipe away any foreign material from the drop counter sensor.
Store in a box at room temperature out of direct sunlight.
Warranty:
We promise to deliver our sensor free of defects in materials and workmanship. The
warranty is for a period of 3 years from the date of purchase and does not cover
damage of the product caused by improper use, abuse, or incorrect storage. Sensors
with a shelf life such as ion selective probes have a warranty of 1 year. Should you
need to act upon the warranty, please contact your distributor. Your sensor will be
repaired or replaced.
Thank you for using NeuLog!
Flexible, simple, fast, forward thinking.
