UP GRADED WITH WIDER LINEUP FM MAG GAUGE METAL TUBE LEVEL GAUGE GENERAL FM Mag Gauge is a float type metal tube level gauge. Liquid level is indicated by clear and visible color flappers. This eliminates problems likely in indication by existing glass gauges. In addition, special material of PVC, Fluorocarbon resin etc. are ready to cover very corrosive liquid level measurement. Alarm contacts and / or analog output unit can be additionally pro- vided for remote monitoring and control purpose. OPERATION PRINCIPLE A float, in which a rounded shape magnet is integrated, is located in a non-magnetic tube (called Chamber). This float moves up and down depending on the liquid level in chamber with specified draft line. Outside of the chamber, an indicator unit is installed, in which plastic magnet rotating flappers are provided. The front surfaces of such flappers are black and the other sides of flappers are co - loured in yellow for every 10mm and red for every 100mm. Then these flappers are rotated by movement of float to indicate liquid level in colour flappers. FM Mag Gauge can be provided with alarm contacts and/or analog output (DC4~20mA) unit additionally onto this level indicator. A reed switch in aluminum case at the setting point is actuated by the magnet in moving float. Water-tight construction, intrinsically safe system with the safety relay,and flameproof enclo - sure are available. The 4 to 20 mA output type has the detection mechanism of float loca - tion (liquid level) along chamber. The detector consists of a series of reed switches and precision type resistances which are actuated by the magnet inside float. The voltage signal of liquid level is converted to 4 to 20 mA signal for transmitting. Water-tight construction and flame- proof enclosure are available.

FEATURES

❏ Metal tube Free from breakage and leakage. ❏ Clear and visible indication By colour flappers, Liquid level in tanks is easily observed even from a distance. Free from blurs and smudges which are common for Glass Gauges. ❏ Covering high pressure and temperature HPGSL*1 approved version is also available. *1 High Pressure Gas Safety Law ❏ Various materials available In addition to standard stainless steel, highly corrosion-resistant materials such as PVC and fluororesin are available. ❏ Full function Indication, alarm contacts as well as analog output. One unit of FM Mag Gauge covers all necessary functions of level monitoring and control. TG-L2262-E05 6th edition Feb 2026 K 1st edition Jun 2022 K

SUGGESTIONS

• On liquid level indication The indicator flappers are actuated by magnet in float. There are different types of float for models, but the position of magnet and actual liquid level (Draft line to float) are different depending on the liquid density. Thus, the position where specific indicator flapper rotates and the position of actual liquid level are different slightly. This gap is fixed and shifted upward in fixed value. This gap (A) is indicated in Approval drawing. The zero line of indicator is to be located above actual liquid zero point by distance of A. Refer to instruction manual for details. Also, be careful for minimum density for the float. Operation prob - lem may occur in case of lower density than designed density. Interface measurement and / or extreme low and high density liquid measurement are available on request. Consult factory for details.
• Heating and heat insulation In case of necessity of heating and thermal insulation for sticky liq- uids etc., thermal insulation is to be provided only for chamber por- tion as shown below. Do not cover indicator, alarm and analog unit by thermal insulation material. The heating or insulation on these parts might causes damages or malfuntioning of indication, alarm or transmitting mechanism. A

12 TOKYO KEISO CO., LTD. Support Indicator window glass Sealed type ・A support is provided when the face-to-face dimension is 2500 mm or more. ・The support material is 304SS. ・Mounting holes on a support are designed for M16 bolts. If M16 bolts are not applicable, M12 bolts can be used instead with plain washers of 12 nominal diameter. ・Standard: Left-side mounting ・When the gauge has a scale plate, the indicator is yellow at 10 mm intervals only. ・When using a capacity scale plate, a tank table is required to indicate both capacity and liquid level. Height scale plate (the scale plate is optional) Example: For 1000 mm measurement range (left-side mounting) Example of character size Material: SUS304 Plate thickness: t=1.5 Background color: White Font color: Black Character size: 6 Scale: Black Measurement range: 1000 Indicator Indicator window glass : A single indicator can cover a measurement range of up to 800 mm. For ranges exceeding this, the indicator is split, resulting in an unmeasurable zone of approximately 30 mm, as shown in the illustration below. Sealed type : A single indicator can cover a measurement range of up to 2900 mm. For ranges exceeding this, the indicator is split, resulting in an unmeasurable zone of approximately 60 mm, as shown in the illustration below.

Note 2: When installing the insulating material, do not install it around the detector. *: For the TIIS flameproof type, mount the flameproof cable gland included in the package, or one of those specified by TOKYO KEISO, directly to the wiring port of the gauge. Use a cable recommended for explosionproof wiring, such as a control cable (JIS C3401) or one with similar specifications. Perform waterproof treatment by applying non-hardenable sealant, such as a liquid gasket, to the connection of the cable gland and the gauge.
