Ultrasonic Liquid Leveller
The Link Instruments ULLC2001 Ultrasonic Level Comparator is one of the most advanced Liquid Levellers on the market. Both extremely easy to use and micro-pic controlled for greater precision in measurement. The transducer is placed against the cylinder body 120mm below the calculated liquid gas level, (normally mathematically calculated). While retaining the transducer at this point the Comparator's ultrasonic level is set to around two or three divisions / bars-¡¡¡, by use of the 0-10 Tune Control. This gives a reference level against which the signal at the gas level / air interface is compared.
By slowly sliding the transducer up the cylinder body, you will arrive at the gas level / air interface. At this point the signal will rise sharply and this is visible on the Comparator usually as all 16 divisions / bars- appear and is due to the enhanced propagation of the Surface Acoustic Wave (SAW), across the liquid gas. |

Enraf’s Field Display & Interface Unit (FDI) provides tank inventory information in the field, where it is needed. It is a versatile, EEx-d approved instrument with several interface options, which can even be part of W&M approved applications.
The design of the FDI is therefore based on reliable and uninterrupted data
supply in all circumstances. The unit can be used in stand alone mode using the Enraf Bi-phase Mark communication protocol for direct connection to an Enraf gauge, or any other gauge using this standard communication protocol in tank farms. The unit will interrogate the gauge and display its measured data.
To update its display in bigger installations where a remote tank inventory
system is available, the indicator listens to the communication between the field instrument and the remote system. When the communication between system and gauge fails, the FDI automatically takes over the scanning of the instrument to provide the measurement data in the field. After sensing the scanning from the system again, it returns to the original configuration. |

Aurora® is the next generation of Magnetic Level Indicators. Its patented design is state of the art in this technology and reflects Magnetrol's subsidiary Orion Instrument’s innovation and commitment to magnetically coupled level indicators.
Aurora is a totally redundant system of continuous level monitoring and control. An Eclipse® guided wave radar coaxial probe is housed along with the MLI float in a 3" or 4" diameter chamber. While the indicator relies upon the float and its internal magnets to activate the flags or shuttle, the Eclipse measures the liquid level directly. Two completely separate technologies in a single external chamber ensure redundancy unlike any other MLI. The use of a baffle plate within the chamber ensures that the float and eclipse coaxial probe work seamlessly within the single chamber.
There are six basic configuration styles and over fifteen material selections for Aurora. For the first time ever, the ability to accurately and reliably measure ultra low dielectric media, high pressure/high temperature process conditions, and media with shifting and changing
dielectric values can be accomplished with Aurora. |

One instrument, three functions: level indicator, level switch, and level transmitter !
WEKA Magnetic Flag Level Indicators provide three important functions in a single instrument, independently of one another: level indicator, level switch (user adjustable over the full range), and level transmitter with electrical signal output. The visual readout does not require electric power supply for its functioning, and indicates liquid level in a vessel through a directly-connected chamber, based on the phenomenon of a liquid having the same level in connected vessels. Level readout is guaranteed in all circumstances. These level instruments are therefore ideal for use during commissioning stages, as well as for back-up functions in process plants.

Comus International has now added to their extensive range of switch and sensor products a range of vertical and horizontal plastic and stainless steel floats.
The range includes vertical and horizontal mounted single and multi float types including the side mounted crocodile type.
The float switches are compact, reliable and very easy to install. They are not affected by electrical interference and with a wide range of materials are able to withstand various chemicals, high temperatures and high pressures. By varying the size of float and material used we are able to make sure the switch activities correctly every time.
The activation of the switch uses the principle of a reed switch and magnet.
When used in the vertical position the reed inside the stem is stationary and the float (housing a magnet) is moved up or down passed the reed switch (this closes the reed contact). When the magnetic field is moved away the reed switch opens.
When used in a horizontal position the float is used in a pivotal movement. The magnetic field inside the float is moved into the proximity of the reed switch inside the stationary stem. The reed switch opens or closes.
For more technical information on these and over 800 switch and sensor products please contact the sales office.
