The assembly is contained in a thermally insulated enclosure to minimise heat losses. The heat flowmeter gives an output to a digital panel meter on the special control and instrumentation console. Special thermocouples are arranged to measure mean temperatures either side of the test specimen, allowing the temperature gradient across the sample and hence the thermal conductivity to be determined. The Thermal Conductivity of Building Material Apparatus uses a PID controlled flat plate electrical heater and a water cooled flat plate with an integral and highly sensitive heat flowmeter. The 300mm *300mm specimen under test is sandwiched between the heated and cooled plates.

A glass sided tilting flume with fabricated all stainless steel bed. Completely self-contained and comprising the working section, moulded inlet and discharge tanks, a series of sump tanks, a pump, an electronic flow meter, a jacking system and a control console. The channel section is fully glazed with large clear panels of toughened glass. A working cross-section of 300mm wide by 450mm deep and available in standard working lengths of 5m, 7.5m, 10m, & 15m. Longer lengths are available to special order in increments of 2.5m. The glass panels are sealed using a rubber section compressed by an aluminum alloy clamping strip. The flume bed is manufactured to high tolerances and designed with an integral web support frame to give the flume a high degree of rigidity and stability. This is coupled with careful design of the side support profiles to provide excellent visibility and allow flow visualization of the full working height of the flume. No under frame or support structure other than jacks is necessary. Rigid dowelled joints are used to connect the sections. The overall strength and rigidity of the design allows excellent stability figures to be achieved and eliminates the need to provide adjusting screws or to perform periodic setting up of the flume to maintain its specification.

This experimental unit forms part of a series of teaching systems developed in collaboration with the Department of Automation and Information Technology at the Harz University of Applied Studies and Research. A fuzzy control is used to move the ball to a specific position quickly and with as little movement of the plate as possible, even when the position of the ball is modified by external influences. A ball-plate model acts as a weakly-coupled mechanical multivariable system. The inclination of the plate is modified by the movements of the respective motors; these movements are transferred to the plate by the drive rod. A joystick can be used to control the system manually. This allows the degree of difficulty of the control process to be estimated very accurately. The position of the ball is measured without feedback using a touch panel and the crisp signals sent to the fuzzy controller, where the signals are transformed into fuzzy input values and inferenced before being transformed back into a crisp output value. Two servo motors act as actuators during this process.

The air flow rate is measured using pressure sensors at discharge orifices at the top of the columns. The two air columns are fed by variable pressure regulators, which can be used to adjust the air flow rate through the column. The integral micro controller calculates the flow rates from the pressure readings and displays these on the front panel.
The apparatus comprises three clear acrylic columns mounted above a moulded ABS base. This column features an overflow pipe, which returns the water back into the sump. The base contains a water reservoir with a variable speed submersible pump, which pumps water through an electronic flow meter into the base of the left hand column.
Pressure drops on all three columns are measured by differential pressure sensors connected to tapping points at the top and bottom of the columns. The software also provides powerful graph plotting facilities. All process measurements are displayed simultaneously on the front panel display and are available on the USB output for data logging.

Self-priming pumps are able to suck in and transport air and water. This is possible because of an additional side-channel suction stage that removes the air from the intake line and creates the negative pressure that is needed to suck in the fluid. In contrast to a simple centrifugal pump, they can also be started if there is air in the intake line.
Learning Objectives And Experiments:
Determination of the system characteristics and the operating point of the pump
Checking of the necessary value of the pump
In combination with recording of pump characteristics
Determination of the pump efficiency
Determination of the power requirement and the hydraulic power.
