To get the flow rate a pre-placed flow sensor resting between these vortices measures. It provides an analog output for flow rate a contact closure output to indicate flow direction and separate pulse outputs to totalize forward and reverse flow. The bend and flex action will then produce an output frequency that is proportional to volumetric flow.
A therms worth of natural gas. The application condition such as high vibration of the piping and pulsating flow is predicted and indicated. Vortex flow meters for steam gas and high-temperature liquids.
Besides mass flow is the first step to calculate the steam energy in custody transfer. Installation Hardware Package Thermowells and the associated installation hardware are provided along with installation instructions to ensure error-free installation and accurate system performance. The air mass information is necessary for the engine control unit ECU to balance and deliver the correct fuel mass to the engine.
Before choosing a flow meter to use in an application a few factors need to be considered. Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect which states that when flow passes by a bluff body a repeating pattern of swirling vortices is generated. Choose from a range of coriolis magnetic turbine vortex piston gear or ultrasonic flow measurement devices.
Typical Accuracy Non. A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. This necessitates the use of relatively long straight piping upstream and downstream from the meter to condition the flow.
