CSA is the Canadian Standards Association which provides product testing and certification for a wide variety of electrical and mechanical products including level sensors for hazardous areas and locations.
Contact T&D for monitoring and level sensing of liquids – products with ATEX and IECEx certification are available including hazardous area float switches, liquid level sensors and load cells.
In North America, hazardous area workplaces and locations have traditionally been defined by a combination of Classes and Divisions:
hazardous area Classes
Class I – a location or area made hazardous by the presence of flammable gases or vapors that may be present in the air in quantities sufficient to produce an explosive or ignitable mixture
Class II – a location or area made hazardous by the presence of combustible or electrically conductive dust
Class III – a location or area made hazardous by the presence of easily ignitable fibers or flyings in the air, but not likely to be in suspension in quantities sufficient to produce ignitable mixtures
Hazardous Area Divisions
Division 1 – a location or area where a classified hazard exists or is likely to exist under normal conditions
Division 2 – a location or area where a classified hazard does not normally exist but is possible to appear under abnormal conditions
North American transition to the
hazardous area zone system
The U.S. and Canada have recently revised installation codes to recognize an international 3-Zone area classification system for equipment used in hazardous locations.
Zone 0 – an area in which an explosive gas atmosphere is continuously present for a long period of time
Zone 1 – an area in which an explosive atmosphere is likely to occur in normal operation
Zone 2 – an area in which an explosive gas atmosphere does not normally exist
In Canada, all new installations must use the 3-Zone system – existing installations may continue to use the 2-Division system or opt to re-classify using the 3-Zone system.
In the U.S., all installations (both new and existing) can either continue using the 2-Division system or re-classify their product using the 3-Zone system.
Should you require any assistance selecting hazardous area level sensors for international classifications including ATEX, IECEx and CSA please do not hesitate to contact us.

Deeter ATEX & IECEX Certified Explosion Proof Range
Deeter LVCS-FP is a flameproof continuous liquid level sensor suitable for hazardous area applications and offers accurate level measurement using a magnetic float with a reed switch or Hall Effect sensor stem.Â
Deeter LVCS-FP level sensor is available in standard length sensor stems from 250mm to 2m and can be custom made to suit up to 4 metres.
Liquid Level & Float Sensors
The Deeter F/S- FP is a flameproof float switch suitable for hazardous area applications and offers flexible switching options using a magnetic float with a reed switch or Hall Effect sensor stem.
The F/S FP float switches are available in a number of standard length sensor stems – additionally up to 7 switch points can be fitted on one stem with a mix of normally open / normally closed switches to suit the application.
Both the LVCS FP level sensor and F/S FP float switch are suitable for hazardous area Zone 0, 1 and 2 applications and can be custom made to suit client requirements and still meet ATEX, IECEx and CSA directives.

Float Switches & Level Sensors
By Chris Dodds : estimated reading time 3 minutes
The Deeter Dual Level Controller is a cost effective solution for the control of pumps and valves enabling effective and accurate control of the liquid level in a tank between two or three set points. The pump or valve is controlled by integrated high power relay contacts.
The Dual Level Controller 2 has an additional relay which can be used for any purpose – such as a low level cut off valve or a high level alarm output. An IP65 version is available.
Deeter manufactures a large range of float switches that are compatible with the Dual Level Controller.
The Dual Level Controller allows control of the liquid level in a tank between two points and/or an extra control output in the event that the tank over or under fills.
The Dual Level Controller (DLC) provides safe low voltage for the level switches which may become submersed and has high power relay contacts to control a pump or a solenoid valve in a gravity fed top-up system.
T&D now provide liquid level sensors and control equipment from Deeter Electronics Ltd including their ATEX, IECEx & CSA approved hazardous area sensors.

Transit Time & Doppler technologies
Clamp on flow meters use Transit Time and Doppler technologies for accurate flow measurement that is non-invasive. Both technologies require two transducers that are installed to the outer surface of the pipe. T&D together with Micronics are able to offer a range of clamp-on ultrasonic flow meter solutions using both Transit Time and Doppler technologies for a range of different applications.
One of the transducers transmits the ultrasonic signals whilst the other receives them.
These transducers are used to create pulses which pass through the pipe.
How Transit Time Clamp on Flow Meters Work?
A clamp on flow meter can accurately measure the flow by calculating the differences in ultrasonic signals of the flowing liquid.
Installing Micronics U1000 Clamp On Flow Meter To Pipe
Micronics specialise in using these technologies to suit most liquid flow requirements.
The Micronics U1000 is a fixed clamp-on flow meter solution for measuring preset flow rate – l/m with a volume pulse output in litres and with a 4-20mA flow rate signal, which can be used as a stand alone meter or as an integral part of an aM&T or BEM’s system.
Micronics Ultraflo clamp on flow meters are simple to install as they easily clamp on to the pipe without requiring the use of any specialist tools.
The Micronics U1000 provides a non-invasive and cost effective flow measurement solution compared to an in-line meter option.
There is minimum downtime for installation or maintenance so there is no interruption to the process.
Compact, rugged and reliable, the U1000 clamp on flow meter has been designed to provide sustained performance in industrial environments.
Contact T&D today to discuss your clamp on flow meter requirements with one of our experienced sales engineers.
