Description
(Product number: HB100C)
The unit uses water filled manometer tubes to determine the pressure at each point across a Venturi and an orifice plate. The water flows through one end and as the cross sectional area changes so does the pressure and velocity in accordance with Bernoulli’s equation.
A horizontal venturi enclosed in a clear plastic cylinder, has 3 pressure point tapings that connect to water manometers. The orifice plate also has 3 manometer tubes that, via quick release connections, connect to pressure tapings across the meter.
The manometers connect to a common manifold that incorporates an air pressure control valve and a hand actuated pump. There is a flow control valve on the outlet portion of the Venturi. The manometers have a graduated scale placed behind them to allow for ease of measurement of the water level. The test section is arranged so the characteristics of the flow through the converging and diverging venturi and the orifice plate can be investigated. The water is fed from the HB100 base unit into each flow meter, and the flow can be measured using the optional HB100K (if ordered).
