Description

The model FSD-4 electronic flow switch offers full flexibility in monitoring and controlling flow based on the velocities of liquid media. The switch points of the model FSD-4 can be freely configured very easily via the 3-button operation directly on the instrument or optionally via IO-Link. The model FSD-4 can output both absolute values in various units and relative flow values and display them on the digital indicator.

Special features

Wear-free flow monitoring of liquid media using the calorimetric principle
Flexibly configurable switching and analogue outputs for flow and temperature
Easily parameterisable via 3-button operation or optionally via IO-Link 1.1
Exact adaptation to the conditions on-site

Accuracy specifications

Accuracy under calibration conditions	The accuracy of the flow switch depends on various parameters such as flow profile, flow conditions, viscosity and/or thermal conductivity of the medium, possible contamination and/ or deposits on the sensor.Therefore, the reference measured values given only constitute an accuracy under calibration conditions. The model FSD-4 offers extensive adjustment possibilities to adapt the instrument to the on- site conditions in the best possible way. As a flow switch it is used for reliable monitoring, for example, of dry running.The flow value output should only be used as a trend indicator in order to monitor process changes.

The in-factory adjustment is carried out with the medium water. It is recommended to carry out the adjustment, relative to the minimum/maximum flow of the system, via the menu.
Temperature	-20 ...+85 °C [-4 ...+185 °F]
Turndown ratio (flow or temperature)	The analogue output signal is freely scalable within the range of 5:1 When setting turndown, there is a proportional increase in the measuring deviation and temperature error.
