Flow Measurement Methods Apparatus (SMT-FM-20)

This unit contains different measuring instruments to determine the flow rate. These instruments are designed with PMMA and are Venturi meter, an orifice plate meter and a rotameter. Bernoulli’s equation works for each meter. Eight tube manometers are used in order to determine the pressure distribution in the Venturi nozzle and in the orifice plate flow meter. 

The experimental unit is positioned easily and securely on the work surface of the SMT-FM- 100 base module. The water is supplied and the flow rate measured by SMT-FM-100. Alternatively, the experimental unit can be operated by the laboratory supply.
