Hazardous Area Level Sensors

In addition to ATEX and IECEx Certification for their range of hazardous area level sensors and level switches, Deeter are now certified to CSA standards for Explosion Proof Accreditation.

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.

Hazardous Area Classifications - CSA

Hazardous Area Classifications – CSA

hazardous areA locations

in North America

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 Dual Level Controller

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

Micronics U1000 Flow Meters (Clamp-on Flow Meter Fixed - Liquid Flow Monitoring)

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.

Transit Time and Doppler Technologies

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

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

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.
