HM 150.13 Methods of Flow Measurement Didactic Equipment Educational Workbench Lab Fluid Mechanics Equipment 1. Introduction to the device
With the HM 150.13, students can become familiar with various methods for measuring flow in pipe systems and apply them in practice.
The experimental set-up contains different measuring instruments to determine the flow rate. These instruments are designed with transparent housings so that their operation and function can be visually seen. The method includes, for example, rotor flowmeters, venturi nozzles or orifice flowmeters and measuring nozzles.
Six tube manometers are used to determine the pressure distribution in the venturi nozzle or orifice flowmeter and measuring nozzle. The total pressure is measured by a pitot tube. The experimental set-up can be easily and securely placed on the working surface of the HM 150 basic module. The water is supplied by the HM 150 and the flow rate is measured. Alternatively, the experimental set-up can be operated via the laboratory water supply. The HM 150.13 flow measurement method unit includes three different flow meters, allowing experimental investigation of the following relationships:
1. Comparison of different flow meters
2. Investigation of the relationship between flow and pressure in flow measurement
3. Determination of the flow coefficient
4. Calibration of the flow meter

3.2 Components
The unit consists of a venturi nozzle (5), orifice plate, measuring nozzle and pitot tube (6) for flow measurement, and a rotor flowmeter (3).
The flow can be adjusted using a gate valve (2).
The pressure loss at the measuring element can be recorded via pressure connection points with quick-action connectors.
These connection points are connected to a 6-tube water pressure gauge (4) equipped with a ventilation valve.
The flow can be measured using the HM 150 base module for fluid mechanics experiments (volume flow measurement).
All bench components are clearly arranged on a framed base plate.
The unit is designed for use with the HM 150 base module for fluid mechanics experiments, which provides the water supply and allows volume flow measurement.
