NEULOG DROP COUNTER SENSOR GUIDE
NeuLog drop counter sensor
NUL-223 Carolina # 369652
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 any of the following guides.
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. Titrations for example
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 uses the following units of measure:
Drops: The number of times a drop of liquid has passed through the drop
counter sensor.
Milliliters (mL): The SI unit of volume. The NeuLog drop counter sensor
calculates the rough volume of the 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 threaded
utility rod which can be attached to various lab equipment to offer many different
orientations in which you can use the drop counter sensor in your lab.
The most important aspect of setting up the drop counter sensor is to ensure that the
drops of liquid are passing through the sensor correctly. As seen in the figure below,
you will want to orient the sensor so that drops will pass through the infrared beam
which is 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
A USB to mini USB cable (which comes with the USB-200)
Your drop counter sensor needs to be connected to a USB-200 module. The USB200 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.
Resident PC software and browser based software can be downloaded for free at
www.NeuLog.com/dowload as well as a full software user guide. Note: Make sure not
to download and install both types of software, they will conflict on the computer.
Procedure:
1. Install the NeuLog software
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 there is no calibration required for this sensor.
4. Open the NeuLog software.
5. Once a drop counter sensor logo 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” button; this will open a graph below.
8. Click on the “Module setup” button located on the drop counter sensor icon
in the module window to change the sensor settings if need be.

9. Click on the experiment set up 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 box to the left of the
screen while plugged in.
11. To run an experiment and collect data click “Run experiment”.
12. To end data collection early, click “Stop experiment”.
Tablet, smart phone device
Materials needed:
NUL-223 Drop Counter Sensor
WIFI-201 WIFI module
BAT-200 Battery
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
module (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 micro USB charger (such as a typical cell phone charger).
The WIFI-201 module will run for 15-75 minutes (depending on the sensor)
without being plugged in.
4. For further WIFI-201 instructions or the WIFI-201 quick start guide please
visit www.NeuLog.com/download.
5. The WIFI-201 indicator lights will flash; take no action until the LED to the
far left turns blue.
6. Take your tablet or smart phone and go to the Wi-Fi settings and select the
NeuLog network which matches the WIFI module ID found on the back of
the WIFI-201 device. (NeuLogXXXX for example)
7. Give your device 1-2 minutes to connect to the WIFI-201 network.
8. Once the device is connected go to your browser and type in the website
wifi201.com into the URL bar, then wait for 30-60 seconds.
9. You will see a “Control mode” icon in the browser, click on this icon.
10. The browser will then load a new screen and begin to auto detect the
sensors, this can take a few minutes.
11. If the browser does not auto detect, select “Search for sensors”
12. Once the sensor is found you will see an icon on the left side of the screen
for the drop counter sensor. The icon will display data in real time.
13. To set the drop counter sensor’s settings click on “Module setup” button
located on the drop counter sensor icon on the left side of your screen.
14. To change the experimental settings click the “Experiment setup” button
(experiment duration for example).
15. To run an experiment and collect data click “Run experiment”.
Operation with NeuLog viewer
Materials needed:
NUL-223 Drop Counter Sensor
VIEW-101 Viewing Module
BAT-200 Battery
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 click the run button (little green
person).
Off-line experiments
(Off-line experiments are for when you do not have a sensor connected directly to a
computer, tablet, smartphone, or NeuLog viewer).
