Tesca Base Digital Hydraulic Bench Module for Experiments in Fluid Mechanics 32097 is of volumetric type and has been designed to provide continuous and controlled supply of water to conduct various experiments using auxiliary modules in typical Fluid Mechanics and Hydraulics Laboratory. The unit is an ideal service unit for conducting student projects. Once filled, no external water supply is required. Water is recycled between the Experiment Module, Measuring Tank and the Storage Tank by the Centrifugal Pump.

Several experiments in Fluid Mechanics and Hydraulics require continuous and controlled supply of water. The Basic Hydraulic Bench provides a controlled recirculation water supply to conduct experiments.

The Basic Hydraulic Bench is a very important module and is recommended for all Fluid Mechanics and Hydraulics Laboratories in Educational Institutions. It is a basic module for flow related experiments using auxiliary modules. Available in non-corrosive, non- breakable long lasting Fibre Glass.

Optional
‘Sci-cal’ Software & Interface: ‘Tesca’ software, interface & related sensors enable plotting of require graphs through the formulae integrated into software. The students can carry out experiments and see graphs and results in ‘Labview’.

Depending on the measurement method, the measured values can be read off the analogue manometer or digital displays. The measured values are transmitted directly to a PC via USB. The data acquisition software is included.

• To run through PC the experiments carried on with the hydraulic bench and the below kits
• The experimental data should be entered manually by the user and processed by software
• Possible to display on video or print the diagrams referred to the exercises can be used in any PC with the following minimum configuration:
• Pentium CPU; HDD, 1G free space minimum; SVGA graphics card; 32 MB RAM; USB port; Operating system Windows 7 or later
