Krohne has introduced a new radar level transmitter for bypass chambers and magnetic level indicators, the Optiwave 1010. The 2-wire FMCW radar level transmitter is designed as a cost-effective solution for the continuous level measurement of liquids in bypass applications in various industries, e.g. chemical, power, water and wastewater, or automotive.
The instrument can be combined with the BM 26 advanced bypass chambers and magnetic level indicators (MLIs), thereby adding a 4-20 mA HART output to these mechanical devices. The combinations can be conveniently ordered as a whole, or alternatively, it can be welded onto the bypass chamber. Thus it is also an ideal solution for other MLI manufacturers to add a level radar measurement option to their product range.
Optiwave 1010 is competitively priced to replace reed chains, magnetostrictive and simple TDR transmitters that are typically used with bypass chambers or MLIs. In addition to a measuring accuracy of 5 mm, the FMCW principle offers a better overall accuracy in bypass applications: while reed chain and magnetostrictive principles are measuring the float position which depends on the product density, the FMCW radar directly measures the liquid surface. The application range includes almost any liquids with process temperatures up to 150°C and 40 barg, with measuring ranges up to 8 m.
The transmitter features a dual process seal system that allows for removal of the converter under process conditions. The 2-wire loop powered HART device is pre-configured in the factory and is delivered ready to use. Application specific adjustments are possible via HART/DD and DTM.
Level measurement of an acid dosing tank at a WWTP
Level Measurement & Control
Ferric chloride and other acids are essential chemical substances in water and wastewater treatment. To control the dosing of acid solutions, an Australian wastewater treatment plant uses a special container to store, mix and add these chemicals. The company opted in favour of KROHNE’s OPTIWAVE 1540 radar level transmitter
