Page 4: Description
Description Thermatel Flow/Level Switches use state-of-the-art thermal dispersion technology for gas flow and liquid flow/level monitoring and control. Flow/level detection is accom- plished by sensing changes in the heat transfer characteris- tics of the media. The sensor is available in 316L stainless steel, Hastelloy C, or Monel welded construction with no moving parts. -
Page 5: Quick Start
Quick Start Unless ordered with factory calibration, the Thermatel switch is adjusted for a level switch between air and water. The set point of the unit must be adjusted for your application. To calibrate for other applications, adjust the set point potentiometer, P1. -
Page 6: Installation
Installation The Thermatel Flow/Level Switch has a standard 3⁄ 4 " NPT Direction of mount designed for easy installation through a threaded Level Movement port. Optional 1" NPT thread mount or mounting flanges are also available. 1. Apply thread sealant to the sensor and insert the sensor into the tee junction. -

2.6.2 Chart Notes and Definitions A. Equipment controlled by Thermatel relay is assumed to be powered from one source, while the Thermatel unit itself is assumed to be powered from a different source. B. “Fail” means a loss of power to the Thermatel unit. C. -
Page 10: Operation And Calibration
Operation and Calibration Note: Calibration should be performed using the actual fluid at the operating temperature. Note: Potentiometer (P3) is set at the factory to handle most appli- cations. The performance of the switch may be changed by adjusting P3: 1. - Page 11 Adjustment procedure VARIABLE FLOW RATE A. Adjust flow to desired switch point: 1. Rotate P2 (delay) fully counterclockwise. 2. Place JP1 (fail-safe) in the “L” position. 3. Establish the flow rate at the desired switching point. Allow 30 seconds for the sensor to stabilize. 4.

8. If the flow can be reduced to the set point, follow pro- cedure A; if it cannot be reduced, follow procedure B. a. Switch on decreasing flow: Slowly rotate P1 (set) counterclockwise until the red LED (D10 or D11) illuminates. -
Page 13: Adjust Set Point
2.7.3 Adjust Set Point Following is a quick guide for adjusting the set point on Thermatel Flow/Level Switch. Process Adjust to detect LED status condition High flow, High level Low flow, Low level Low flow — Low level — o Turn P1 clockwise until LED is off. High flow o Turn P1 clockwise until LED is on. -
Page 14: Advanced Calibration Procedure
2.7.6 Advanced Calibration Procedure Measure and record the voltage between TP1 and TP2. This voltage will change with set point and may be used for future reference or adjustment of set point. 2.7.7 Power On Delay The TSF/TSL switch incorporates a “Power On Delay.” When power to the switch is first applied, there is no temperature difference between the two sensors, causing a high flow or high level alarm. -
Page 15: General Information
General Information Maintenance 3.1.1 Cleaning The probe may be cleaned by soaking, spraying solvents or detergent and water onto the sensor tubes, or by ultra- sonic cleaning. Lime deposits may be safely removed by soaking in 20% hydrochloric acid. Warming to +150° F is permissible to speed this process. -

3. Loosen the screws on the four position terminal block (TB1) to remove the leads from the probe. 4. Unscrew probe from enclosure. Installation of replacement probe (Refer to Figure 6 on page 6.) 1. The probe's leads have been separated at the factory. Connect leads from RTD #1, which are grouped and marked, to the two terminals on TB1 closest to the sensor label (refer to Figure 6). -
