Page 3: Introduction
Introduction CF12 AC / CF12 DC Thermal Dispersion Flow Switch Monitor The CF12 series of thermal flow switches is designed to monitor flow status of liquids and gases and can also be used to detect level. A chain of 8 LED's gives the user a visual indication of the flow status of the switch. There are... -

Page 10: Pre-Installation
Pre-Installation Pre-Installation Checks: Fig. 1 1) Its recommended that the flow switch is installed with a distance of ½ a meter of the pipe bent where the flow enters and 5x times the 1/2m 5xØ diameter of the pipe where the flow exits, enabling it to have an accurate reading (Fig. -
Page 11: Installation
In pipes with smaller diameters use an adaptor to enlarge the diameter of the pipe so that the sensor Fig. 5 can be properly installed (See Fig. 6). If the installation is not correct the CF12's performance may be affected. Fig. 6 www.sitron.com - email: info@sitron.com... - Page 12 Calibration To Start: 1 - Remove the enclosure lid (Note: the screws are self-retaining) 2 - Start the power supply and wait 5 minutes until the CF12 is active and has reached a stable point within the medium. 3 - Let the regular or desired flow reach its point of normal operation. Calibration for Flow / No Flow: 1 - Set the flow rate at the normal range of operation.

2 - Continue to turn potentiometer clockwise until all green LEDs in the bar graph turn on. 3 - In order to be sure that the adjustment is not at a critical state give the potentiometer an additional quarter turn clockwise. www.sitron.com - email: info@sitron.com... -

Handling Seal the thread with Teflon tape before installation (Fig. 1). Fig. 1 Do not turn or handle by the housing (Fig. 2). Use the correct tool during installation (Fig. 3) The CF12 should not be dropped or suffer any impact or fall that could damage the electronics or the thermal tips of the probe (Fig. -
