|
The
Flo-Check USB represents the next generation of hydraulic test equipment.
The device simultaneously measures flow, pressure, temperature and power within
a hydraulic system. This data is displayed and logged through a custom Windows®-based
software application; data is received from the Analyzer through a standard
USB cable (both software and cable are included with the unit). The Flo-Check
USB is ideal for testing, troubleshooting and diagnosis in mobile and industrial
hydraulic applications, and for setting hydraulic components such as pumps,
valves and motors. The unit is bi-directional and includes a low-resistance
load valve and internal pressure relief discs. |

| Overview |
The
Flo-Check USB Hydraulic System Analyzer can be used as a stationary or portable
tester for both industrial and mobile hydraulic system diagnostics, and analysis
of the prognostic health of a hydraulic system. It features flow, pressure,
and temperature sensors that are monitored by a data acquisition module. This
module records the operating parameters of the system and transfers them to
the user’s laptop via the USB port. The custom software utility is a
Windows®-based application which is compatible with Windows Vista®,
Windows XP and Windows 2000. This intuitive software configures the displayed
information into user-selected engineering units and provides real-time graphics
with instantaneous readings and trends for all three measurement parameters.
The software also permits the data to be saved for export into a spreadsheet
program. The Hydraulic System Analyzer is powered through the USB port of
a PC, making it easy to setup and ideal for portable applications. Interfaced
to the PC application, the Hydraulic Analyzer offers a straightforward method
of monitoring system parameters complete with data acquisition. |

| Software |
The Flo-tech Analyzer software provides a real-time graphical and digital interface for monitoring and/or recording pressure, temperature, and flow rate parameters from the Hydraulic Analyzer. In addition to the graphical and digital displays, the main screen also consists of a menu bar, buttons with common functions, and alarm indicators. The software offers the following options:
|
|
 |
|
All
measurements taken (as shown in Table 1) can be saved once per second to a
comma separated value (.csv) file for export into a spreadsheet program. For
example, recording for 2 minutes would yield 120 points of data. Even though
data points are only recorded once per second, pressure spikes and dips are
captured by recording the maximum or minimum pressure during each measurement
period. Therefore, the precise shape of the pressure spike is not recorded
but its amplitude and the time it occurred are both recorded. |
|
 |
|
| Graphs
The
graph on the main screen contains more than 60 points of data. Previous data
points are saved in memory and can be viewed at any time. Adjustments can
be made to optimize data that is displayed by hiding individual graph plots,
adjusting the scale of each plot or adding horizontal gridlines to the graph.
Alarms There are three sets of High/Low alarm indicators on the main screen that monitor pressure, temperature, and flow rate. Alarm indicators flash if the current system measurements exceed the alarm limits set by the operator; they continue to flash when the current system measurements return to normal, to alert the operator that an alarm condition occurred. Alarms must be reset manually to acknowledge the alarm condition. |
