This product supplies a controlled flow of water to a wide variety of laboratory experiment modules (available separately). The body of the bench forms a reservoir or ‘Sump Tank’ with a submersible pump. Once filled, the bench needs no external water supply.
The top of the bench provides a working surface. This will hold one of a choice of experiment modules from TecQuipment’s Fluid Mechanics range. Larger experiments usually stand next to the bench. A rim around the top contains any spilled or excess water. A small recess or ‘Trough’ in the top works with a removeable Drain Valve to trap a small volume of water. It also catches discharged water from some experiments in the fluid mechanics range.
A hand-operated control valve adjusts the water flow rate from the pump. An electrical box on the side of the bench includes the pump switch, circuit protection and a digital display of flow.
Four wheels allow the user to move the bench around the classroom. Two wheels have foot-operated locks to hold the bench in position.
A sight gauge to the lower side of the bench allows the user to check the water level inside the tank.
An electronic flowmeter measures the outlet flow from the submersible pump. The signals from the flowmeter pass to the digital display to show the flow rate. The viewing angle of the display allows the user to see it clearly from a normal standing position.
East Tennessee State University, which has a history of teaching engineering technology dating back to the 1930s, made the decision to expand the course offering in 2015 to include a BSc in General Engineering which combines courses from mechanical, civil and electrical engineering. To teach the course they needed an engineering laboratory that had equipment to practically teach the principles of civil and mechanical engineering. There were existing electrical engineering laboratories, to serve the BSc, in the electrical engineering technology programme. After going out to bid, TecQuipment won, based on a balance between price and functionality of equipment.
