Technical content

The FM4000 series metal tube level gauges are improved versions of the FM-1000 series level gauges that Tokyo Keiso has been manufacturing for many years. Liquid level is indicated by rotating fl appers in an indicator by the action of a magnet integrated in a fl oat. Alarm switches and/or analog output (4 to 20 mA DC) transmitters can be additionally provided for on-site checking and remote monitoring and control purposes. Specifi cations for the high pressure gas certifi ed product, PVC, or fl uorocarbon resin linings are the same as those for the FM-1000 series.

FEATURES

❏ Metal tube (FM4100 to FM4800) All pressure-resistant parts and wetted parts are made of metal and hence free from breakage or liquid leakage. ❏ Clear level indication Fluorescent color flappers enable easy observation of liquid levels even from a distance. Indicators are free from blurs and smudges that are common with glass gauges. ❏ Three functions by a single gauge (on-site indication, alarm, and level transmission) In addition to on-site indication, an alarm switch and an analog output (4 to 20 mA DC) transmitter can be additionally provided for minimizing the total cost of level control. ❏ Operable under harsh conditions Pressure: Max. 40 MPa Liquid temperature: −196 to +400ºC Measurable liquid density: Min. 0.39g/cm Interface measurement: Density difference 0.2g/cm 3 and density sum 1.2g/cm 3 or higher (These gauges cannot withstand the combination of maximum values.) ❏ Manufactured to meet customers’ specifi cations Gauges can be manufactured to meet customers’ specifi cations such as connection size, measurement range, density, and vent and drain designs. Contact us for details. ❏ High-performance analog output (4 to 20 mA DC) transmitter using magnetostrictive effect High-precision analog output (4 to 20 mA DC) transmitter using the magnetostrictive effect can be additionally provided. Conforms to Japanese, IECEx, ATEX, and Chinese explosion- proof standards. ❏ Explosion-proof alarm switch Conforms to Japanese, IECEx, ATEX, and Chinese explosion- proof standards. OPERATION PRINCIPLE A float with an integrated magnet is located in a metal tube (chamber). This fl oat moves up and down depending on the liquid level in the chamber with a specifi ed draft line. In an indicator unit, rotating flappers made of plastic magnets are arranged at every 10 mm. The front surfaces of the flappers are black and the other surfaces are colored in yellow at every 10 mm and red at every 100 mm from a reference position. These flappers rotate and their colors change due to the movement of the fl oat, thus indicating the liquid level. Alarm switches and/or an analog output (4 to 20 mA DC) transmitter with a magnetostrictive sensor can be provided additionally onto this level indicator.

  • A support is provided when the face-to-face dimension is 2,500 mm or longer.
  • The support material is 304SS.
  • Mounting holes on a support are designed for M16 bolts. When 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 comes with a scale plate, the flapper indication color is yellow only at every 10 mm.
  • For using a capacity scale plate, a tank table is required to see both capacity and liquid level. Indicator Indicator window acrylic : A single indicator can cover the measurement range of up to 4,800 mm. Indicator window glass : A single indicator can cover the measurement range of up to 800 mm. When a wider measurement range is required, an indicator is separated into two parts resulting in a no indication zone of about 30 mm width, as illustrated below. Sealed type : A single indicator can cover the measurement range of up to 2,900 mm. When a wider measurement range is required, an indicator is separated into two parts resulting in a no indication zone of about 60 mm width, as illustrated below.

  • The FM Mag Gauge indicates liquid level by flappers that are rotated by the action of a magnet integrated in a float. Several types of floats are available according to the density of the liquid to be measured. However, as the liquid density increases from the design lower limit, a gap occurs between the actual liquid level (float draft line) and the position of the built-in magnet. This gap does not change even if the liquid level changes. Therefore, in practice, the indicator is displaced upward to compensate the gap (indication gap A). The red flapper at the indicator bottom is aligned to the actual zero position of the liquid level. Refer to the gap value (indication gap A) described in the delivery specification.
  • When the liquid level goes up or down faster than 2 cm/s, flappers may fail to follow the movement of a float and fail to rotate. In such a case, use the attached magnet to restore the correct indication. When the tank pressure or temperature fluctuates rapidly, bumping (abrupt generation of gas in liquid) may occur, causing an abrupt rise of the float and a jump in the indication. A double tube may help prevent this phenomenon. Contact us for details.
  • To use this gauge in vacuum, be careful about abrupt pressure changes in the tank or level gauge. The float may jump up to the end and cause damage.
  • Select the float so that the density of the liquid to be measured does not fall below the design minimum density of the float. Density changes may have to be taken into account if the temperature changes significantly. Contact us for the cases of values not described in the code table or interface measurements.
  • The compatibility between the liquid to be measured and the gauge materials should be checked by the customer.
  • The liquid to be measured must be free from sticking or freezing.
  • A magnet is integrated in a float. In an iron-rich (or rusty) environment, ferric substances may adhere to the magnet, causing malfunction. Periodic inspection and cleaning are recommended.
  • When a chamber needs heat insulation, for measuring sticking liquids for example, make sure that the heat insulation does not enshroud the indicator, as shown in the Figure. Likewise, alarm switches and magnetostrictive sensors should not be covered by heat insulation. If the indicator and sensors are covered by heat insulation, the gauge may become hot and may fail. Use non-magnetic materials (that do not react to a magnet) for heat insulation, protection, and fixing hardware.
  • When implementing wiring to alarm switches and magnetostrictive sensors, seal the wire outlets so that water or moisture does not penetrate into the devices.
  • Indicators, alarm switches, and magnetostrictive sensors of Mag Gauges work by the action of magnets integrated in floats. When installing a Mag Gauge, make sure that no magnetic substances or substances made of iron that reacts to the magnet in the float are near a level gauge. The presence of such substances may cause malfunction.
  • Use of a gauge under an environment subject to harsh impact or vibration may cause malfunction or failure. Indication gap A Alarm switch Heat insulation Chamber Tranceducer （20） Indicator Detector Do not cover around indicators, alarm switches, transducers, or detectors with heat insulation.
