 Magnetic Level Gauge – BM 26 A
 
Bypass Level Indicator
The proven mechanical-based solution for level indication
  • Most compact bypass level indicator on the market
  • Robust, stainless steel design
  • Permanent, IP68 local indication without power supply

The BM 26 is a simple, rugged instrument designed to indicate level or interface. It indicates level using a float magnetically coupled to an index or a column of rotating flaps. It is ideal for aggressive media stored in tanks when the PTFE lining option is used.
 
For liquids with densities less than 0.5 kg/l / 31 lb/ft³, pressures more than 120 bar / 1740 psig and temperatures higher than 300°C / 570 °F, we recommend our BW 25 displacer-type level indicator.
 
Highlights
  • Stainless steel design (optional NACE conformity)
  • Proven technology
  • Temperature range: -200...+300°C / -325...+570°F
  • Pressure range: -1...120 bar / -14.5...1740 psig
  • Density: 0.5...3 kg/l / 31...187 lb/ft³
  • Float material options: 316L, 316 Ti and Titanium

  • Less risk of leakage than a sight glass - little or no maintenance needed
  • Easy to install
  • Ideal for tanks with obstructed environments
  • Optional indication of interface
  • Optional approvals for EEx i or EEx d applications

 Magnetic Level Gauge – BM 26 BASIC | ADVANCED
 
Stainless Steel Bypass Level Indicators for applications up to 40 bar / 580 psig
  • Best price / performance ratio
  • Full stainless steel construction
  • IP68 local indicator with bold colours and an optional stainless steel scale

Our bypass level indicators are simple, rugged devices designed to indicate or transmit the level of liquids. They indicate level using a float magnetically coupled to a column of rotating flaps. Bistable switches can be attached to the measuring tube to detect level.
 
The Basic version is ideal for measuring liquids with a density ≥0.75 g/cm³ / ≥46.8 lb/ft³, temperatures up to 150°C / 300°F or pressures up to 16 bar / 232 psig (for more data, refer to Guidelines for maximum operating pressure on page 37). Level can also be transmitted via an ER analog transmitter.
 
The Advanced version is ideal for measuring liquids with density range of 0.54...2.0 g/cm³ / 33.7...124.8 lb/ft³, temperatures up to 300°C / 570°F or pressures up to 40 bar / 580 psi (for more data, refer to Guidelines for maximum operating pressure on page 37). Level can also be transmitted via an ER analog transmitter or Radar/TDR level transmitters.
 
Highlights
  • Stainless steel design, including indicator rail (Hastelloy® C-276 as an option)
  • Proven technology
  • Less risk of leakage than a sight glass - little or no maintenance needed
  • Easy to install
  • No power required - permanent local indication
  • Indicator is isolated from process (magnetically-coupled)
  • Conforms to the latest European construction standards (NACE as an option)
  • Optional approvals for Ex i applications
  • Optimal construction: weight is kept to the minimum

Industries
  • Chemical
  • Oil and Gas
  • Petrochemical
  • Water

Applications
  • Low- and medium-pressure storage tanks
  • Process tank
  • Separators
  • Distillation tank

 Magnetic Level Gauge – BM 26 F
 
Bypass Chamber with integrated Guided Radar (TDR) Level Meter
The solution for tanks with obstructed environments
  • Ideal for tanks with obstructed environments
  • Measures level, interface, and level and interface
  • Optional remote housing provides the user with an unrestricted view of the display screen

BM 26 F is based on proven bypass measurement technology. It is capable of high precision measurement and is unaffected by foam, agitated product surface and obstructed tank environments. BM 26 F integrates the OPTIFLEX 1300 C Guided Radar (TDR) Level Meter for distance, level and volume measurement of liquids and liquid/liquid interface. It can also optionally indicate level using a permanent, IP68 local indication without power supply.
 
For pressures 40...120 bar / 580...1740 psig and temperatures 200...300°C / 390...570°F, we recommend using our BM 26A bypass level indicator. For pressures more than 120 bar / 1740 psig and temperatures higher than 300°C / 570°F, we recommend using our BW 25 displacer-type level indicator. For further information on the integrated Guided Radar (TDR) level meter, please refer to the Technical Datasheet for the OPTIFLEX 1300 C.
 
Highlights
  • Configured system - easy to measure
  • Measurement independent of density
  • Ideal for tanks with obstructed environments
  • PACTware and DTMs included as standard
  • Measures down to dielectric constant of 1.4
  • Display in 9 languages: even in Chinese, Japanese and Russian
  • Housing is removable under process conditions

Industries
  • Oil & Gas
  • Petrochemicals
  • Power
  • Water

Applications
  • Process and storage tanks
  • Steam crackers
  • Boilers

 Magnetic Level Gauge – BM 26 W
 
Magnetic Level Indicator with integrated Radar Level Meter
The measurement solution with built-in redundancy
  • Can easily be isolated from the process
  • Two measurement principles in one device
  • Autonomous local indication with an IP68 ingress protection rating

BM 26 W is based on proven bypass measurement technology. BM 26 W integrates the OPTIWAVE 7300 C FMCW Radar Level Meter for distance, level and volume measurement of liquids. It can measure level in a variety of difficult conditions: foam, agitated product surface and obstructed tank environments. It also indicates level using a permanent, IP 68 local indication without power supply.
 
For pressures from 40 to 120 bar / 580 to 1740 psig and termperatures from 200 to 300°C / 390 ... 570°F, we recommend our BM 26A bypass level indicator. For pressures more than 120 bar / 1740 psig and temperatures higher than 300°C / 570°F, we recommend our BW 25 displacer-type level indicator.
