Vortex inline flow measurement with integrated PT1000 temperature monitor

Vortex sensors measure flow through the turbulence generated by the water as it passes through it. Depending on its speed, it generates turbulence inside the body, the signal is read through of a piezo ceramic sensor. This method of measuring the flow rate, is based on the Karman vortex principle. Is completely independent of pressure and temperature fluctuations in the medium.  The flow generates a current signal (4 … 20 mA), the PT1000 probe is integrated in the flow meter. Optionally, an analog pressure sensor (4…20 mA) can be installed.  The sensors used are mounted in the return line of each circuit.

Flow measurement by piston with PT1000 temperature sensor

The flow sensor works on the principle of a spring loaded piston. Piston rests on valve seat, lifts up due to force that exerts the flow of the fluid against the piston spring. The analog signal of (4… 20mA) is determined through the position of the piston. The force of the spring ensures the piston returns to its starting position when the flow slows down. This allows the flow sensor to de installed in any orientation and prevents backflow. The temperature probe it is not integrated in this type of sensors, allows us to work with high temperature range up to 180ºC. The temperature is measured by a PT1000 thermocouple. Optionally an analog pressure sensor (4…20 mA) can be installed. The sensors used are mounted in the return line of each circuit.

The multiple flow distribution system is used to measure and control the volumetric flows of liquid media, it is characterized by its variability, its compact and robust design. Our modular system allows us to offer you a solution that meets your specific needs, being very easy to install.
