Level Measurement & Control


Continuous level measurement

July 2019 Level Measurement & Control

DRH Components is the official distributor of Bindicator bin level sensors in South Africa. These prevent overflow spills, controlling surge bins, detecting blocked chutes and providing on/off control of pumps and conveyors in the dry bulk industry.

Bindicator offers a full range of point and continuous level measurement products certified for hazardous and normal atmospheres. The diaphragm type AB-S is the original electromechanical point level switch. Diaphragm-type level controls were the first to enjoy general usage in the industry. These simple

devices eliminate bin overflow, empty bins, clogged conveyors and blocked chutes, preventing damage and waste to plant and product. The diaphragm sensors are available in various sizes and have six different types of diaphragms to suit most dry bulk applications.

Point level products, such as the Roto-Bin-Dicator PRO paddlewheel and the VRFII Series capacitance probe are on/off devices with relay contact outputs. Point level sensors indicate when material in a vessel is present or absent at a specific point. These durable, simple devices are easy to install, they don’t require calibration or special tools, and they need little or no maintenance.

Continuous level measurement products from DRH Components continuously monitor the level of material in a vessel as it rises and falls. Bindicator has a variety of products available such as TDR2000 guided wave radar that provides continuous, non-mechanical level measurement utilising guided wave radar technology. The TDR-2000 is particularly suited for measuring the level of solids, granules and powders, as well as a wide range of liquids. The Yo-Yo Series cable and weight bin level sensors are specifically designed for continuous level measurement of a dry bulk solids inventory. Available as an option, the Yo-Yo Readout is an LCD display that can monitor up to 99 sensors and is used to program each cable and weight.

The F78MP Series through-air radar is accurate and reliable in difficult environments. The F78MP Series air radar sensor withstands corrosive environments and takes consistent measurements in steam, dust and other turbulent conditions. Outputs for most continuous level sensors include relay contact, 4-20 mA and PLC interface, with various fieldbus connectivity options.
