Level Measurement & Control


Dry product level measurement range

February 2005 Level Measurement & Control

Solartron Mobrey is offering a range of level products for dry materials. Developed as a direct result of customer demand throughout Europe, the range includes three switches and an ultrasonic non-contact transmitter for reliable control of dry materials used in industrial processes. Customers requiring both dry and liquid level measurement can now purchase products from one source; reducing time spent researching, ordering and maintaining new equipment.

The new products provide continuous level measurement and point level detection of dry materials used in the chemical, aggregates, pharmaceutical, plastics and food and beverage industries. Solutions are available for materials ranging from 80 kg/m3 density (such as powdered carbon) to 2,5 tonnes/m3 density (aggregates and gravels) and for hazardous, aggressive or high temperature environments. The products, which have relevant IP ratings, enable customers to match a solution to their specific requirements and budget.

The Series ULT ultrasonic non-contact transmitter is the most advanced device within the range. It provides accurate and reliable level measurements of all dry materials from very low to very high densities including sludge and slurries. With ranges of 15 m, 30 m and 60 m available, the transmitter measures the amount of dry material within a vessel by sending an ultrasonic wave to the top of the material that returns an echo back to the transmitter. An aiming device allows the installer to position the transducer face perpendicular to the angle of repose of material in the vessel to ensure accurate measurement. HART communication is available.

The Series CLS capacitance level probe is based on proven dry level measurement technology. It can be used with any free flowing granular, pelletised or powdered dry product and because it has no moving parts and includes product build up compensator electronics, it is also ideal for difficult dry products which have a tendency to coat or build-up, such as animal feed and foundry sand. A range of different probe sizes to suit a variety of mounting positions is available.

The Series VSL vibrating rod is based on the most modern point level detection technology and is ideally suited to free flowing powders and granules. It also has no moving parts and is a robust instrument that can be used in corrosive materials and in atmospheric pressure environments of up to 10 bar.

The Series PLS paddle level switch is simple to use, easy to maintain and able to deal with materials of very high density such as that found in aggregates, gravels and earth - all of which have a bulk density of over 2 tonnes/m3. It is based on proven dry level measurement technology and is mounted from the outside of the vessel to a curved or flat surface.

The Solartron Mobrey range is brought to southern Africa by Dupleix Liquid Meters (DLM), a leading instrumentation specialist. In addition to a comprehensive product offering, DLM offers a full service backup including engineering design, supply, installation, commissioning, calibration and ongoing servicing of all Solartron Mobrey products. DLM has seven branches countrywide - in Cape Town, East London, Pinetown, Rustenburg, Welkom, Vereeniging and Polokwane - in addition to its headquarters in Longmeadow, just outside Johannesburg.
