LEVEL SENSORS (Bulk, Liquid, Chemicals)
This range of data loggers provide easy, efficient and reliable data acquisition over a wide range of level control applications. These units can be installed on a new or existing site to operate with any level controller and can be configured either locally or remotely via a PC with the aid of DATAFLEX software. This system is suitable for numerous logging applications including remote level monitoring of liquids and solids in any tank, vessel or silo and with the option for alarm relays to trigger external telemetry systems in remote areas.

 This principle of operation is quite simple. The transducer is located at the top of the vessel and transmits a pulse of high frequency sound energy down to the tank.  The sound wave is reflected off the surface of the material to be measured and this echo returns back to the transducer, the time it takes is proportional to the level or distance.  This technology is simple, easy to install and relatively low cost.  Ranges up to 50m can be measured.

 
liquiflex_and_multiflex Measurement using ultrasonic 'through-the-air' principles has been widely used in the process industries for many years, but it has its limitations with regard to the application. Pressurized vessels, varying gas densities and surface foam can all cause loss of the echo signal!
This new non-contact ultrasonic instruments are capable of monitoring levels with novel 'through the wall' techniques which overcome these fundamental problems.
This enables level measurement in totally enclosed vessels without the need to enter or cut into the tank or silo. These systems can provide a wide range of control options, from single point level switching to continuous level measurement and can be installed on a wide range of applications including hazardous and aggressive media. 		  REFLEX RADAR provides cost effective 2 wire technology for both TDR and FMCW systems to meet the ever increasing demands of industry in the 21st century. These systems are already well proven in a wide variety of liquids and solids applications and overcome the difficulty of mounting and maintaining instruments at the bottom of a tank. Do not confuse these 10Ghz FMCW instruments with other lower frequency PULSE instruments. FMCW technology gives superior performance for "through air" radar instruments. This range of instruments provides unique 2 wire TDR "Radar on a Rope" of FMCW "Through air" solutions to many level control problems.

Model: WM-LEVSNRS-HYCL-002
This laser based sensors exploit the unique properties of light to produce precise and reliable measurements.  A high precision counter measures the time of flight of the laser pulse to and from virtually any target. An integral microprocessor then calculates the distance and averages a number of shots to produce an accurate reading. Distances up to 250m can be measured.   This contact range of vibrating level probes provides single point switching which is capable of detecting levels of solids, powders, granules and flakes, whilst being unaffected by in-flight material.  This design incorporates one oscillating leg within another,  and this eliminates the common 'bridging' problem associated with other vibrating fork designs, which can cause false signals.

PROBLEM
 Carbon dioxide is a natural byproduct of many processes and it is used extensively by industry and in particularly by the brewing trade both in production and for pressurizing beer and soft drinks in pub cellars.
Despite its many advantages CO2 does have a major disadvantage: it is a colorless, odorless gas which is heavier than air and can be very dangerous in an enclosed low lying area. Quite simply, anyone entering such an area can quickly and without warning lose consciousness.		   SOLUTION
This carbon dioxide monitor is a simple and cost effective method of providing both a visual and audible indication of abnormally high levels of C02 in an enclosed environment.
The instrument consists of a sensor which monitors the ambient air mixture and the temperature surrounding it and then computes the percentage of C02 in the air. The sensor tube is mounted in the risk area and connected via a cable, to the alarm controller located outside the high risk area. This provides, to anyone considering entering the risk area, an audible and visual indication when the C02 levels are high. The controller also has the facility to activate a relay Which can operate a second light or audible alarm, which may be located in an external Such as a control room or bar, or it can be used to switch off the C02 supply or switch on ventilation fans.		    

Model: WM-LEVSNRS-HYCL-005
Features:
No maintenance, uses solid state electronics and has no moving parts.
Simple push button recalibration of zero. Traffic light warning systems enable corrective action to be taken in case Of C02 leakage.		        
  low cost for multiple monitor in one location.
Easy installation  just screw it to the wall and connect the wires provided. Self Diagnostics - The display gives a message which indicates the cause of a failure.

   C02 SENSOR
This is mounted approximately one metre above floor level in the area subject to C02 leakages. it is connected to the controller via a 10 metre cable which is supplied with the sensor. This cable can be extended using standard 4 core screened cable.

5A SPDT		   MULTI CHANNEL CONTROLLER
This is the lowest cost solution for large buildings with C02 stored in several places. This instrument can be selected to monitor up to three sensors in three separate locations. A single cable goes from the controller to each sensor using conventional junction boxes as shown below.
The sensor number lights indicate which location is being monitored and the alarm status lights for each location remain active whilst the instrument is scanning the other two locations.
The specification for each channel is the same as the single channel instrument. Manual selection of an individual channel is possible for calibration purposes.
