DESCRIPTION The C9-MKII Flowmeter Demonstrator is designed to allow the user to understand the different types of flowmeters commonly found in use throughout various industries. The flowmeters available are of both electronic and non-electronic types with the options covering both mechanical and passive systems. The experimental content includes the measurement of pressure loss across a range of flowmeters and the direct use of flowmeters for the determination of flowrates, either visually or by the use of pressure differential. The unit is supplied with armBUS software as standard. Including manual data entry for non electronic flow meters and automatic datalogging for electronic flow meters. (Requires AIU-4) The unit can be used to: Understand the practical use and characteristics of Industrial flowmeters Assess the pressure drop which occurs with flowmeters within a simple piped system Understand flow measurement by using flowmeters which relay on a pressure change across the system The unit comprises of a framework that incorporates pipework with valves, a reference flowmeter, water and digital manometers and a test section for the insertion of flowmeters undergoing testing. The unit is designed to utilise the F1-10 Hydraulics Bench which provides a pumped reservoir of water to recirculate through the C9-MKII unit making efficient use of water. The flow rate of the system can be varied by use of a simple control valve to study the effects of changing flow in relation to pressure loss in a flowmeter The optional AIU4 Interface Console links the flowmeters with electronic outputs to the laptop or PC. The console interprets the signals received into the correct output format for the armBUS™ software. The console has a 24vDC power supply to reduce the risk of high voltage incidents with contact with water TECHNICAL SPECIFICATIONS Digital Differential Manometer Operating range – 0 – 2000 mBar (0 – 1500mmHg) Water Manometer – Operating range – H12-2 1000 mm H2O Electromagnetic Flowmeter – 50 – 200 ltr/min.
