Thermal dispersion flow switch CF12


thermal dispersion
for liquids, for gas
Other characteristics
compact, stainless steel, aluminum, insertion, threaded, IP65


The CF12 series is a line of thermal dispersion flow switches. It is designed to monitor the flow status of liquids and gases. A visual indication of the flow status of the switch comes in the form of a series of 8 LED’s. Two red LED’s tell whether the unit has detected a flow, a yellow LED shows the set point, and five green LED’s indicate the amount of flow beyond the unit’s set point. Included in the device is a red/green LED which shows the switch point status of the unit. A 316 stainless steel is used to connect the sensing element and the CF12. Available in either glass-filled nylon or aluminum enclosures, all models can also be ordered with a variety of process connections. Application: Flow for liquids and gas level for liquids only Operating Voltage: CF12 AC: 85-240Vac (50/60hz) 125Vdc and CF12 DC: 24Vdc (+/-10%) Current Consumption: +/- 100mA Output: Relay (SPDT) 5A – 250Vac Set Point Range: Liquid: 3 cm/s to 3 m/s – Gas: 5 cm/s to 5 m/s Accuracy: +/- 10% Repeatability: +/- 1% setpoint Response Time: 1 to 10s Gradient Temperature: 15ºC/min Flow Rate Indication: Red led – Flow is below setpoint / Yellow led – Flow is at setpoint / Green led – Flow is above setpoin Enclosure Material: Glass filled nylon Electrical Connection: Cable gland w/ 2000mm cable, M12 connector or ½” NPT Process Connection: BSP or NPT, adjustable, sanitary or flanged connections Wetted Material: 316 Stainless Steel or Halar coating for corrosive media Operating Temperature: 14 to 176º F (-10 to 80ºC) or extended neck to 248ºF (120ºC) Max Pressure: 100 Bar (others upon request) Class Protection: IP 65 (IEC 60529)
