EF Series By-Pass Liquid Level Gauge
More than just another level measurement company …
Aplus Finetek Sensor, Inc. PRODUCT INTRODUCTION
OPERATING PRINCIPLE The EF Series is a liquid level gauge that is installed on the outside of a tank or other vessel. The EF can provide any combination of a local visual indication of liquid level, single or multiple level switch output and a continuous level transmitter output.
The EF series by-pass liquid level gauge utilizes hydrostatic buoyancy principles to indicate liquid level. A float with a built- in fixed magnet inside travels up and down inside the by-pass chamber according to the changing level inside the tank. A visual flag indicator is attached to the chamber to provide local visual indication of the liquid level inside the tank. Each individual flag has two colors, one on each side, and a magnetic element. The magnetic flags will flip as the float inside the chamber passes by each flag going up or down and indicates the liquid level.
Several switch types are available that are magnetically actuated. These switches can be mounted attached to the outside of the chamber at the desired switch activation point. As the magnetic element inside the float passes by the level switch, the built-in reed switch will change state. Level transducers can also be attached to the outside of the EF chamber and will provide analog and/or digital outputs. The EF series by-pass liquid level gauge can provide the functionality of a local visual indicator, a level switch and a level transmitter all in a single device. These optional accessories and example assemblies of the EF series are illustrated here on pages 9 and 10.

18 IMPORTANT INSTALLATION NOTES
1. The Adjustable type EFB-14 99 series magnetic switches are installed on the adjusting rod provided with EF assemblies when ordered with these switches. The adjusting rod is then fastened to the chamber with two hose clamps (refer to page 10, Fig. 3). 2.The Standard type EFB-1299 series and the Explosionproof Enclosure type EFB-1399 series magnetic switches are to be fastened onto the chamber with a hose clamp. They will come installed onto the assembly with new EF series liquid level gauges (refer to Fig. 4 here and page 10 Fig. 1 and 2). Position magnetic switches as shown in Fig. 5 here. 3. Handle the magnetic switches carefully. The magnetic switch incorporates a sensitive internal component, the reed switch, and as such it is subject to potential damage from any extreme impact. 4. Make sure there is no external magnetic field or source within 4” (10cm) of the switch in order to avoid magnetic interference. 5. Make sure the wiring of any magnetic switch is pointed downward. Fig. 4 6. Ensure that switch wiring is not in contact with any high temperature material. 7. When the magnetic switch is being used to control inductive or capacitive loads care must be taken to ensure long life. An RC protective circuit Position Orientation Of should be used to ensure long life (refer to page 20). Magnetic Switches 8. The magnetic switch must be mounted close to the flag indicator to ensure the internal magnetic reed switch is in appropriate proximity to the magnet Flag display in the float within the chamber. The magnetic switch must be mounted so 60 the surface of it is directly contacting the outer surface of the chamber. 60 Refer to Fig. 5 here. 9. Check and ensure all wiring is complete and correctly done before actuating the switch. Magnetic switch 10. Refer to Fig. 6 here for the installation direction of mounting holes. 11. A “fixed holder” is recommended to be used and installed between the center-to-center flanges when the C-C distance is greater than 60” (1.5m). To ensure best stability of the EF assembly, the maximum distance between two fixed holders or between a connection flange to a fixed holder cannot exceed 39.4” (1m). Aplus Finetek can provide these fixed Fig. 5 holders if requested. Refer to Fig. 7.

20 EF SERIES BY-PASS LIQUID LEVEL GAUGE ORDER INFORMATION
† Notes: 1. All EF series magnetic liquid level gauge units are marine grade approved DNV, Lloyd’s Register, Germanischer Lloyd, BV and ABS. If marine certification is required on data label please specify this requirement in description of EF unit when ordering. 2. To order the HIGH TEMP INSULATION BLANKET type simply select the complete part number from the order information below and specify in the order description that the fireproof insulation blanket is required. If the 752⁰F (400⁰C) temperature rating is required with the insulation blanket, specify selection “C” in the Chamber material and max. temp. rating category. 3. To order the STEAM JACKET HEATING type select “8” Process connection in the End/connection type category and specify this type in the part description when ordering. 4. To order the FREEZE PROTECTION type select “D” in the Chamber material and max. temp. category and specify this type in the part description when ordering.
