Level Measurement

Float type Level meters

Magnetic Metal tube Level meters

Sales Temporary discontinuation

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 flappers in an indicator by the action of a magnet integrated in a float.
Specifications for PVC or fluorocarbon 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 +400℃
  Measurable liquid density: Min. 0.39 g/cm³
  Interface measurement: Density difference 0.2 g/cm³ and density sum 1.2 g/cm³ or higher
  (These gauges cannot withstand the combination of maximum values.)
• Manufactured to meet customers’ specifications
  Gauges can be manufactured to meet customers’ specifications such as connection size, measurement range, density, and vent and drain designs. Contact us for details.
• Certification for high-pressure gases
  Gauges certified for high-pressure gases are available on request (up to 9.9MPa).
  Contact us for details. (The actual structure may differ from the drawing.)
