1. INTRODUCTION
The HydroTablet consists of software developed and
supported by Hydrological Services combined with the
respected “Samsung Galaxy Tab Active”hardware (Model
SM-T360), especially designed for harsh environments and
use by tradepersons.
The Tablet communicates via Bluetooth to the Hydrological
Services’ CMCsp, PVD100, PVD200 and MAG1 Current
Meter Counters.
Direct water velocity measurements may be taken, or full
river gauging data may be collected, calculated, displayed
and emailed back to the office.

2. MAINTAINENCE
The HydroTablet does not require much maintenance, but a few simple precautions will
ensure a long life for this product.
2.1 Connector / Socket Care
The Galaxy Tab Active is
submersible to 1m for 30 minutes.
If the device is accidentally dropped
into the water, remove quickly and
dry with a soft absorbent towel.
Make sure the connector sockets
are free from water, dust and dirt
before plugging in the charging
lead.
2.2 Battery Care
The Galaxy Tab Active contains a rechargeable 4.45Ah
battery which can be recharged via a standard 5V USB
wall or car charger. This battery is also replaceable.
2.3 Touchscreen Care
The touchscreen of the Galaxy Tab Active is a capacitive type, and may be damaged if
not treated with a little care.
DO NOT use a ball point pen or pencil or sharp object to touch the screen.
DO NOT use excessive pressure when touching the screen.
A very light finger pressure is all that is required to perform a touch –or the supplied
touchpen may be used.

3. OPERATION
The HydroTablet Application is started by pressing the HS icon in the Home screen. The
application operates in Portrait mode. In addition to the LCD being “sunlight readable”, most
screens have been created using black text on a white background, with a large text size to
make it more easily readable when in the field.
3.1 Operator Options / Settings
Click on the
Options button
Set the required
calculation method
and units.
The email address
and “observed by”
operator will be
auto filled into the
forms –but the user
will be given the
choice to change
these later.
See the next section
for setting the Fan
equations.
Press the HS
Icon to start the
Application.

3.2 Fan Equations / Selection
Some Fans have 1, 2 or 3 calibration equations :
3 Equations : Enter all 3 equations and inequalities as shown above.
2 Equations : Enter 1 of the equations twice. Assume equations are : V=0.6564n+0.0094 n<0.14
V=0.6981n+0.0035 n>0.14
Enter them as : V=0.6564n+0.0094 n<0.14
V=0.6981n+0.0035 0.14<n<0.15
V=0.6981n+0.0035 n>0.15 (make this inequality bigger than the first)
1 Equation : Enter the same equation 3 times. The inequality doesn’t matter, so just set it to n<1.00 n>2.00
When in the
Options menu,
click on the Fans /
Meters button.
Press on + to add
a new Fan.
Adding a Fan :

Appendix C Discharge Calculation Methods
In both methods the mean water velocity in each vertical is calculated by using the weighting
table shown in Appendix A. For example, if 3 water velocities are measured in a single
vertical, they would be measured at depths of 0.2D, 0.6D and 0.8D. The mean velocity of this
vertical would therefore be : Vmean = (V0.2D x 0.25) + (V0.6D x 0.50) + (V0.8D x 0.25)
The following sketch shows a typical discharge with depth measurements d0, d1, d2, d3, …
taken at each vertical (note d0 is the depth at the bank, usually zero, but may be non zero) –and
the distance between the verticals b0, b1, b2, b3,…..calculated from the distance from the
reference point - and the mean water velocity v1, v2, v3, …. calculated for each vertical.
These measurements are then used to calculate the discharge using either the Mean Section
method or the Mid Section method.
*** PLEASE NOTE ***
Each method will yield slightly different results, as described on the following pages.
