Product overview
The portable velocity system is used in the field, laboratory and municipalities. Turbulent, noisy and
low flows can be measured with this system.
6 English

When the sensor is placed in flowing water, a magnetic field around the sensor creates a voltage
proportional to the flow velocity. This voltage amplitude, which represents the rate of water flow
around the sensor, is detected by electrodes in the sensor and processed by the sensor
microprocessor. The processed signal is digitally transmitted through the sensor cable to the portable
meter and the information is shown on the meter display. The system includes a portable meter,
sensor with cable and accessories.
The meter and sensor get velocity information in conduits and streams. These measurements are
important for calibration in municipal wastewater industries, as well as for developing and maintaining
stage discharge relationship curves.
Two types of sensor are available: velocity-only and velocity plus depth. This manual covers both
types of sensors. If information applies to a specified type of sensor, this fact is noted in the text.

of Real Time information. The velocity is updated in FPA filter mode according to fixed period
averaging time. In RC filter mode, the velocity is updated continuously on the screen every
250 ms.
Option Description
Capture Stores the depth and velocity information shown in memory. The information is saved until
power is cycled, the memory is saved to a non-volatile real-time file, or the user exits from real-
time mode.
Save Saves captured measurements in the volatile memory to a non-volatile real-time file. A
message will show if the number of files is greater than the maximum possible. Files are
stored in tab delimited (.tsv) format.
Done or OK Exits the real-time mode and returns to the Main Menu. If there is unsaved data in volatile
memory, a confirmation message asks the user to confirm the exit without saving the data.
Clear Clears captured measurements from the volatile memory buffer. The user can choose from
Clear Last, Clear All or Cancel options.
Setup Allows the user to modify the main filter parameters and enable and program the Maximum
Depth sensor positioning feature. The Maximum depth feature allows a user to enter system
parameters for depth measurement in Real Time mode. The user can choose to enter a
maximum depth value taken directly with a ruler measurement (manual), or taken indirectly
with the depth measurement (automatic). Both methods enable the Maximum Depth sensor
positioning feature.
In automatic mode setup, the user directly enters the distance from the bottom of the channel
to the bottom of the sensor mount (offset). The setup interface will continuously show the
current depth value returned by the sensor plus the offset. The meter stores this value as the
Maximum Depth when the OK button is pushed. In all other cases, the depth values shown do
not include the offset.
The Maximum depth feature requires a sensor with velocity plus depth.

English 15

Option Description
Filter
parameters
Applies a data acquisition filter (Main filter or Pre-filter). The user can select the filter
parameters.
Main filter
• Fixed Period Averaging (FPA)—Fixed Period Averaging averages data over a user
selectable fixed period of time (1 to 480 seconds). The default is 30 seconds. If the FPA
value is 5, the velocity value shown in the display is updated once every 5 seconds.
• RCA time constant—The RC filter helps smooth out turbulence through the use of a
selected time constant in the filter algorithm. This mode is useful when searching for a
maximum velocity, for example in the common 0.9 x Vmax profile method. High RC filter
time constants give higher degrees of smoothing. The time constant can be set from 2 to
20 seconds, with a default value of 6. At 1 time constant, the filter settles to
approximately 60% of the final value. At 5 time constants, the filter settles to 99.9% of
the final value. Thus, if the RC value is set to 2, the final value shows after 10 seconds.
Pre-filter
• Median filter—The filtering process is done in the sensor. The feature can be disabled.
However, the recommended (default) value is 5. Enable the feature to enter or change
this value.
Wet/dry
threshold
Sets the sensor submersion threshold for wet and dry conditions. The default value is 20%.
Refer to the appendix in the expanded version of the manual for more information.
Auto zero
depth
Sets the Auto Zero feature to On or Off.
If set to On, the instrument does an air calibration when the sensor is removed from the
water and is in the air. To do the air calibration, the instrument automatically zeroes the
sensor.
If set to Off, the user can manually zero the sensor. To do this, remove the sensor from the
flow, then push and hold the Quick Jump key for five seconds.
When the sensor has been in the flow for 30 minutes, the green circle in the upper right
corner goes from green to red. This is a prompt to the user to remove and zero the sensor
again.
EMI Sets the local line frequency for ambient noise rejection to 50 Hz (default) or 60 Hz .
Clock Sets the date and time of the portable meter in 24-hour format. Daylight savings time is not
supported.
USB Sets the USB mode.
• Mass Storage (default)—This mode operates like a memory stick or hard drive. Files are
read-only.
• CDC—This mode is used to update firmware.
Language Selects the language used in the menus.
Units Sets the units for velocity, flow and depth measurements. Options are Metric (default) or
English .
Beeper On (default) or Off. If set to On, the meter makes an audible tone when the sensor is at the
correct depth for applicable profile methods. The meter also makes an audible tone when
an inactive button is pushed in any menu. This feature is available only with the optional
depth sensor.
Flow
calculation
Selects the method of flow calculation for open water segment (stream profiles only).
Options are Mean-section or Mid-section. Refer to the appendix in the expanded version of
