Mass Flow Measurement
Dense Flow
For unlimited volumetric throughput measurement in dense phase pneumatic conveying lines. There is no flow restriction in the conveying line and the measurements are independent of the velocity of the material. The DenseFlow is available from 10 NB to 125 NB. It is a maintenance free unit and the high pressure unit can be installed with line pressures of
Maxx Flow
Designed to measure the mass flowrate for high capacities. It has a completely open cross section and low installation height of 300mm, therefore can easily be installed in the process. It can be placed in a vertical or inclined pipe, but always after mechanical equipment such as a feeder or conveyor.
Some of the benefits of the MaxxFlow are: no upper limit on throughput volume, max pressure of 10 bar and 120˚C, totally dust-tight, product not in contact with measuring process, wear resistant since it is internally lined with a ceramic tube.
The MaxxFlow is ideal for filling of tankers and trucks that are not standing on a weighbridge. This allows an accurate mass to be discharged. The MaxxFlow can also be installed in pneumatic conveying lines to measure the product flow
Pico Flow
This unit was designed for low conveying capacity, it essentially operates above a dust measuring device, typically from 100 g/h to 100 kg/h with a minimum flow velocity of 2 m/s. This unit is inserted into the air stream and can be used in both metallic and non-metallic pipes (the latter requires a metallic shield around the outside of the pipe
Solid Flow
Used for continuous mass flow measurement of dry powders or granular products from a few kg/h up to a maximum of 20 t/h. The sensor does not obstruct the flow of material and is installed flush with the ID of the pipe or duct. Very fine powders from 1 x 10-6 mm to 10 mm can be measured
Moisture Measurement
M-Sens
Used to measure the moisture content of product in hoppers or equipment (screw conveyor or belt conveyor). This can be done continuously or periodic. The unit is robust, has a protective ceramic disc to protect wear of the sensor. It is suitable for dust, powder, granules and other types of bulk product
Level Monitoring
ProGap
Microwave technology enables contactless level detection of dry products in pipes, tanks and containers. Detection is possible through non-conductive materials and with a ceramic adaptor can withstand temperatures up to 1000 ˚C. The ProGap is insensitive to material build-up and can be used over a distance of 25 m
Dust Measurement
Dusty
Used to detect dust particles suspended in a gas stream, such as on the clean air side of a dust filter. The Dusty continuously measures any dust particles. When a pre-set level is exceeded, an alarm output is triggered. The unit can also be easily upgraded providing a 4-20 mA output thus allowing trends to be measured
AirSafe
Installed in work places to measure the dust concentration present in the surroundings. Typically this would be installed for early detection of dust that could be hazardous to humans or reach a concentration where it could become combustible and cause an explosion. The AirSafe could be installed to prevent dust explosions such as in a grain mill
ProSens
Enables dust to be measured in large ducts and even at high temperatures up to 700˚C, making it the ideal solution for exhaust ducts of large bag houses or furnaces. The ProSens can provide an absolute value or be used to record trends
SpeedFlow
Used to continuously measure the speed of dust, powders or particles in metal ducts or pipes in free fall or pneumatic conveying applications. The minimum velocity that can be measured is 0.75 m/s up toamaximumof35 m/s. The system provides a 4-20 mA output signal
FlowJam
The sensor is used to detect flow in a duct, chute or even a cyclone. The unit is insensitive to material deposits, it can be used for almost any pipe diameter, with a ceramic adaptor t is possible to install it for process temperatures up to 1000 ˚C. The FlowJam can detect flow through non-conductive walls. The FlowJam Plus is able to distinguish whether a no flow detection is due to no material present or a material blockage
SlideControl
Used to measure and detect flow in an air slide without making contact with the material. The SlideControl uses microwave technology to measure the distance between the sensor and the flowing material. With this information it can calculate the mass flow rate by assuming a constant velocity. The sensor will also detect if the material stops moving or there is no material present
Paddy
Used to measure particle sizes downstream of a screen in a free fall pipe arrangement. Essentially it consists of two sensors, the first being a reference sensor and the second the measuring sensor. If a screen beak occurs, the Paddy will immediately detect this. The standard unit can detect particles up to 10 mm in size (larger ones on request). The special measuring tube is available from 100 mm to 200 mm ID and requires a 450 mm installation height
