Operation
The IM series in-line flow switch is designed to easily adapt to ¼” tubing. Please refer to the IX or FX series for larger line sizes. These switches offer an extremely reliable and repeatable instrument for industrial process control and feature no moving parts exposed to the product being monitored. The device operates by measuring a temperature differential between a heated and a reference temperature sensor. Within the body of the sensor head are the four tubes as shown in figure 1. The temperature differential is greatest at no flow and changes as flow is achieved across the sensor. This allows use in applications requiring a simple flow/no flow detection and for set-points at a predetermined flow rate. Many different flow ranges are shown in the set-point range section. A conversion table is also provided to convert different engineering units.
Extremely low flow rates can be detected with a typical turn down ratio of 300:1. The principle of operation allows this flow switch to be used in practically all liquids, gases and slurries.
The electronics are available with single or dual switch points. The instrument can be easily field programmed to detect an increase or decrease of flow. Relay outputs are standard and are offered with several different configurations and contact ratings.
