.jpg) | Non-Contact Ultrasonic Level Meters – OPTISOUND 3010 C - 3030 C Ultrasonic Level Gauges For Liquids OPTISOUND 3010 C, 3020 C and 3030 C ultrasonic sensors are especially suitable for level measurement of liquids, but are also good for solids. The instruments differ in the measuring range, the transducer version and the process fitting. Through different, adapted emitting frequencies, levels in a measuring range of 0.25 m ... 15 m (0.82 ft ... 49.2 ft) can be measured. Resistant materials for transducers and process fittings also allowa pplications in corrosive products (depending on the model). A practical mounting strap (option) enables easy orientation of OPTISOUND 3030 C. OPTISOUND 3010 C The application range covers liquids and solids in virtually all industries, especially in the water and sewage water treatment treatment. Measuring range liquids: 0.25 - 5 m solids: 0.25 - 2 m Process connection: G1˝A of PVDF Process temperature: -40 - 80°C Process pressure: -0.2 - 2 bar OPTISOUND 3020 C The application range covers liquids and solids in virtually all industries, especially in the water and sewage water treatment treatment. Measuring range: liquids: 0.4 - 8 m solids: 0.4 - 3.5 m Process connection: G2A of PVDF Process temperature: -40 - 80°C Process pressure: -0.2 - 2 bar OPTISOUND 3030 C The application range covers liquids and solids in virtually all industries. Measuring range: liquids: 0.6 - 15 m solids: 0.6 - 7 m Process connection: compression flange or mounting strap Process temperature: -40 - 80°C Process pressure: -0.2 - 1 bar Additional Info: http://krohne.com/en/products/level-measurement/non-contact-level-meters/optisound-3010-c-3030-c/   | ||||||||

The instruments differ in the measuring range, the transducer version and the process fitting. Through different, adapted emitting frequencies and effcient transducers, levels in a measuring range of 0.6 m - 45 m (1.97 ft - 147.6 ft) can be measured. Resistant materials for the transducers and process fittings also allow applications in corrosive products (depending on the model). OPTISOUND 3030 C The application range covers liquids and solids in virtually all industries. Measuring range liquids: 0.6 - 15 m solids: 0.6 - 7 m Process connection: compression flange or mounting strap Process temperature: -40 - 80°C Process pressure: -0.2 - 1 bar OPTISOUND 3040 C Solids applications Measuring range: liquids: 1 - 25 m solids: 1 - 15 m Process connection: flange with optional swivelling holder Process temperature: -40 - 80°C Process pressure: -0.2 - 0.5 bar OPTISOUND 3050 C Solids applications Measuring range: liquids: 0.8 - 45 m solids: 0.8 - 25 m Process connection: flange with optional swivelling holder Process temperature: -40 - 80°C Process pressure: -0.2 - 0.5 bar Additional Info: http://krohne.com/en/products/level-measurement/non-contact-level-meters/optisound-3030-c-3050-c/ | ||||||||
.jpg) | Potentiometric Level Gauge – BM 500 Potentiometric Liquid-Level Measuring Device
The BM 500 level gauge operates on the potentiometric measuring principle and is designed for use in all electrically conductive products with a minimum conductivity of 1 µS/cm (e.g. distilled water). This method is particularly suitable for measuring levels in small vessels containing viscous, pasty or heavily caking products. The electronic evaluation unit is integrated in the connecting head and supplies a level-proportional output signal of 4 ... 20 mA. The HWM 500 hygienic process welding sleeve ensures installation in conformity with standards of hygiene. Due to its high temperature resistance (140°C / 285°F), the BM 500 is eminently suitable for CIP cleaning and sterilizing processes. Applications
Measuring Principle The measuring principle is comparable to that of a slider potentiometer, with in this case the liquid representing the slider pick-off. An alternating current is applied to a stainless steel tube to cause a drop in voltage via the electrical resistance of the tube (cf. slider path). The conductive wall of the vessel forwards the tapped voltage conducted through the liquid to a high-resistance amplifier. Based on the supply voltage, this yields the ratio between the depth of immersion and the total length of the tube. Together with the high-resistance pick-off, this ratio explains why the measuring system is independent of the conductivity of the product. Sticky deposits merely form a parallel connection with the anyway very low-resistance tube. What is measured, therefore, is only the actual product between tube and vessel wall. | ||||||||
