A Blast Furnace Radar is a microwave range finder that consists of a controller, a guide pipe and an antenna.
It is important to control the distribution pattern of charged raw materials to ensure a more stable operation and improve the reaction efficiency.
MWS-20RF-2H
The main advantage of the Semrad Pty Ltd blast furnace radar MWS-20RF-2H is that it is completely unaffected by heat, flames, dust, vapour and shock (note this only applies to the reflector and guide pipe, however the controller and antenna need to be installed in normal temperature areas). The controller can withstand temperatures between -10 and +50 degrees and the antenna can withstand temperatures between -20 and +150 degrees. The MWS-20RF-2H responds 4 times faster than WADECO standard Microranger. This means that the measurement of bath levels can be carried out quickly and more accurately. It increases operating space due to the fact that the reflector retracts back into its original position (through the use of a robotic arm) when it is not in use. The robotic arm mechanism also eliminates the need for wiring and construction.
The MWS-20RF-2H has a range of built in functions such as:
- A reference point and the required range are easily preset.
- Compatible for use with a personal computer.
- Power supply range of 90∼240V, 50/60Hz.
- Communicates with a Personal Computer by RS-232C.
- 4-20mA, analogue output.
- RS-422 digital output terminals (distance, receiving power level, temperature and alarm).
The MWS-20RF-2H can detect a range of up to 50 meters and has an accuracy rate of 3mm.
All WADECO products come with a 1 year guarantee period from the date of delivery.
Hydrostatic Pressure
Hydrostatic pressure is the pressure at any given point in a static fluid. Pressure in open conditions (e.g. the ocean, the atmosphere, a pond) can be approximated as the pressure in static conditions, since the motion of currents or waves create only negligible changes in pressure. It is the same at any given point because otherwise the fluid would move in the direction of the resulting force.
According to the principles of equilibrium, the pressure of a liquid at rest is isotropic, meaning it acts with equal magnitude in all directions. If a point in the fluid is thought of as an infinitesimally small cube, the pressure of every side of this unit of fluid must be equal. This characteristic allows fluid to transmit force through the length of pipes (a closed condition).
Hydrostatic pressure is useful for determining the levels of liquid in a tank, among other things, using devices such as a hydrostatic tank gauge.
Hydrostatic Bubbler
Semrad Pty Ltd offers a range of industrial level gauges, sensors, switches and transmitters. Their WaterLOG® H-3531 FlashLite™ is a NIST traceable pressure sensor. It combines low cost with high accuracy, as it can directly measure dry gas with accuracy better than 0.02% FSO. It comes with built-in temperature compensation, with an operating range between -40° and +60°C.
This non-submersible pressure sensor has an easy to use Simple RS-232 Menu Interface, and a non-conductive and corrosion proof enclosure. Its SDI-12 output provides measurement data in engineering units (e.g. feet or meters), it is easy to use with the H-355 Gas Purge System and is compatible with the RS-232 Data Logger. It also features extended SDI-12 command for setting the stage to the correct water elevation or pressure. It operates on low currents and deviates less than 0.02% from a staight line referenced to end points.
Oil Separators
An oil separator is a large drum designed to separate production fluids into oil, gas and water. These three components have different densities, meaning they stratify when moving slowly. Gas works it way to the top, water falls to the bottom and oil stays in the middle. The oil and water are separated by a baffle set at the height of the oil-water contact. This allows the oil to spill over the side, trapping the water on the other.
Valves on the oil and water outlets are controlled to ensure the interfaces are kept at optimum levels for separation to occur. Oil separators are used for bulk separation as droplets of water will not settle by gravity and will remain in the oil stream. To remove the last of the water the oil is routed to a coalescer. Any solids will drift to the bottom and this sludge is removed with a mechanical scraper or a sludge pump.
Water and oil separators are used throughout industry, with the oil either being further refined to develop petroleum or the water purified and pumped back into a reservoir or the sea.
Alarm Sensors
Oil separator alarm sensors indicate when the sludge deposit or layer of oil or grease needs to be emptied. The alarm is the only way to be sure when it is economically sound and environmentally safe to collect the hazardous waste.
Semrad’s Oilset 1000 and 2000 are interface level detectors for oil, water, sand, sludge and grease. They feature reset and test functions, no moving parts, high accuracy, a large display, no calibration needed, and explosion proof models. The alarm is audible, can operate in temperatures between -30° and +55°C, and the cabling between controller and sensor can reach up to 3m. They are wall mounted sensors whose internal buzzer and external alarm can be muted. The direction of the alarm can also be changed.
