Series TDS Thermal Dispersion Flow Switch

Adjustable Switch Point, LED Indication

The Series TDS Thermal Dispersion Flow Switch offers solid state flow detection of non-coating liquids for pump and processprotection. SPDT output allows for interfacing with remote PLC or relay control device. The adjustable switch point is factory calibrated at 0.2 fps with LED indication of flow and calibration status. Units feature selectable NO or NC operation and are not damaged by over-ranging flow velocities.
