JUMO PINOS L02 Calorimetric flow sensor

www.jumo.in

The JUMO PINOS L02 flow sensor measures and monitors flow velocities of liquid media. The measurement method is based on the calorimetric measuring principle and does not include any moving parts which can influence the flow profile negatively. The measuring principle is based on the cooling of a heating element. Due to the flow behaviour of the liquid, heat is taken from the temperature probe. The higher the flow velocity, the higher the heat emission of the heating element. The resulting measured value can be output via an analog output of 4 to 20 mA or open or close a switching output. A device version with analog and switching output is also available. Both output variants can be configured for the output of the flow velocity or the medium temperature. The status of the device is displayed using 3 LEDs.

The JUMO PINOS L02 can be used for a nominal pressure up to 75 bar and in an admissible flow range of 0 to 300 cm/s.

To allow for simple startup of the flow sensor, it is equipped with a micro-USB interface while a setup program is also available as an accessory. A switching point can be set on-site using a push-button on the user interface. The push-button can also be used for flow calibration if the process requirements (for example, medium, flow velocity) do not correspond to the default settings. Due to its robust design with protection type IP65/67, the flow sensor can also be used in difficult environmental conditions.

The main areas of use are the monitoring of cooling water circuits, pumps, heat exchangers, lubrication circuits, leakage monitoring for process lines, and dry-run protection for pumps.
