SP/SF Series Flow Switches

PRODUCT INTRODUCTION – SP SERIES

1

The SP Series is a thermal dispersion type flow switch. The SP is a precise flow sensing device whose principle of operation is heat diffusion. The SP series sensing probe incorporates two primary components. One component is a heated sensor with power applied to it. The second component measures the temperature emitted from the heated sensor. When the fluid is flowing a temperature difference will exist between the two sensor components. This temperature difference has an inverse relationship with the fluid flow velocity, e.g.the faster the fluid flows, the greater the temperature difference will be and vice versa. This method of flow sensing is accurate and highly reliable given the absence of any moving parts, which minimizes wear and tear.

1. Install the SP series thermal dispersion flow switch using the sealing gasket provided with the unit.2. Refer to Figure 1. The distance “a” must be at least 4 times greater than the pipe diameter the SP

series flow switch is installed in.3. Refer to Figure 2. To ensure proper operation of the SP series flow switch, make certain that the

flow switch probe Is completely immersed in the fluid flow and that the pipeline is free of any entrained air.

4. Refer to Figure 3. If the pipe the SP is installed in will not contain a full pipe flow, install the SP flow switch to the bottom of the pipe (horizontal pipe).

5. For best sensitivity, speed of response and overall operation, install the SP series flow switch in the orientation to the flow stream as show in Figure 4.

6. Installing a filter upstream of the SP flow switch is recommended if the fluid contains impurities as this can increase life by reducing abrasion on the switch probe element.

The SF series flow switch is capable of detecting the flow of liquids in pipes. It is an electromechanical device, reliable and cost effective. When the liquid is not flowing within the pipe, the spring (item 5 in drawing) is fully extended, pulling the magnet (item 6) downward and opening the reed switch. As flow of the liquid occurs and the paddle is thrusted forward by ³20⁰~30⁰ the paddle will push the magnet upward and actuate the reed switch, thereby closing the circuit. The length of the paddle can be adjusted during installation to best fit the pipe’s diameter.

1. The paddle length is to be cut during installation. The length should be that which will extend the paddle into the pipe to the lowest point in the pipe for switch activation. Cut the paddle to the appropriate pipe size as marked on the paddle or wherever desired. The minimum is 1” pipe size *

2.The SF flow switch must be installed so that the paddle is at a right angle to the flow of the fluid in the pipe.

3.The SF flow switch must be installed so that the “FLOW” mark on the process connection will be parallel to the pipe.

4.Before installing the unit apply thread sealant and then tighten.

5.Height of mounting coupling on pipe should not exceed 1.25” (32mm) from inside wall of pipe or 0.874” (22.2mm) from outside wall of pipe. **

1. The operating pressure and temperature limits as shown in the SPECIFICATIONS table must not be exceeded. Verify before installation.

2. Large and sudden changes in fluid temperature and density (specific gravity) will influence the flow switching accuracy.

3. Shock and vibration should be minimized in order to ensure long life.

4. Excessive debris within the fluid may inhibit paddle operation. Periodic maintenance should include re-moval, inspection and cleaning if required.

5. Properly sealing the conduit entrance and process connection will minimize or eliminate damage due to moisture.
