Rototherm group has acquired the assets and Intellectual property of Canongate Technology the Edinburgh based Level & Density instrumentation and CO2 analyser specialist.

 

Canongate Technology product range has been using ultrasound in a variety of applications for over 20 years. Its products include CarboCheck, Blend Check, Densi Check and Vessel Check.

 

Canongate Technology products are used in Beverage, Refigeration, LPG and Pharmaceuticals sectors, and the products are installed throughout the world.

 

Our level products include:

 

Embra CarboCheck In-line Dissolved CO2 Analyser

 

VesselCheck - Non-invasive Tank Level Measuerment Systems

 

SpotCheck - Non-Invasive Point Level Detector for Tanks & Pipes

 

 

Embra CarboCheck System 2000

 

General Application

 

As the world’s leading CO2 monitor and control system, Embra CarboCheck uses the well known saturation pressure / temperature technique for accurate, non-sampling measurement.

 

Embra CarboCheck can be used for measurement alone or configured as a control system.

 

Working Principle

 

The CarboCheck sensor features a silicone rubber membrane, through which the dissolved CO2 permeates into a sealed, evacuated chamber. The partial pressure of the gas is then measured and displayed by the analyser / control unit as a CO2 content.

 

The system incorporates a vacuum exhauster to regularly evacuate the sensor, providing continual, accurate measurement of dissolved CO2. The analyser / control unit can be linked to a carbonation system to enable fully integrated CO2 measurement, injection and control.

 

Typical Applications

 

• Beer carbonation ex-filter

• Mineral waters carbonation

• Sparkling wines carbonation

• In-line CO2 monitoring on brewery and soft drinks packaging lines

• Carbonation of pre-mixed drinks

VesselCheck

 

General Application

 

VesselCheck is a highly versatile and accurate range of non-invasive liquid level measurement systems, comprising a signal processing unit and ultrasonic transceivers.

 

Working Principle

 

Ultrasonic sensors are clamped or bonded to the outside walls of the vessel; one on the bottom of the vessel, with the fully density compensated option, one on the side. Signals from the transducers are fed into the processor and either displayed locally, if that option is selected, or output to a separate system. The system calculates the height and volume of the liquid in the tank, from the time taken for the signal to be received from the liquid surface.

 

VesselCheck - Benefits

 

• Fast, reliable and accurate tank contents measurement

• Not affected by pressure

• Easy installation - no tank break-in, easy retrofit to existing tanks

• No down-time during installation

• No moving parts – little or no maintenance required

 

Features

 

• Ultrasound technology proven for over twenty years

• Fits tanks of most shapes and sizes above ground

• Truly non-invasive sensing technique

• Sensors bonded to outside of tank base and side wall

• Optional local display and/or output to higher level system for up to two tanks

• ATEX approved versions for hazardous areas available

SpotCheck Series 1000/2000

 

General Application

 

SpotCheck is a liquid level switch for use in applications where avoiding contact is vital. The sensor is clamped externally to the wall of the pipe or vessel. The method of measurement is suitable for steel, plastic or glass up to 50mm thick.

 

Working Principle

 

SpotCheck uses an ultrasonic “footprint” to determine the presence of absence of liquid inside a tank or pipe. It provides two wire, 24Vdc operation with an appropriate current sensor but also incorporates a relay switch output.

 

The piezo-electronic transducer emits ultrasonic energy into the wall of the tanks or pipe, which acts as a wave-guide. The electronics detect the difference between “wet”, “dry” and “fault” conditions.

 

In order to ensure that SpotCheck will operate satisfactorily, the surface of the tank or pipe must be prepared properly.

 

Typical Applications

 

• Tank high / low level alarm

• Non contact level switch

• Overfill procedure

• Pump run dry protection

• Pig Detection

• Tanker off-load pump control

• Liquids with suspended solids and free gas

• Detect liquid / foam interface

• Aggressive or toxic liquids, effluent, sewage etc.

• Hygienic level switch for hygienic liquids, foodstuffs, pharmaceuticals, chemicals

• Flowing and static liquids

• High or low pressure pipes or vessels

• Detect presence of spray e.g. Tank washing
