KROHNE introduces the new TIDALFLUX 2300 F for flow measurement in partially filled pipes. The electromagnetic flowmeter features an integrated, non-contact capacitive level measurement and an approval for ATEX zone 1 for use in hazardous environments, especially for the German waste water market.
New TIDALFLUX 2300 F: flow measurement solution for partially filled pipes
KROHNE has year of experience in flow measurement in partially filled pipes: TIDALFLUX 2300 F continues the line of TIDALFLUX flowmeters which have been in the market for more than 16 years. The new TIDALFLUX 2300 F is designed to provide reliable flow measurement for flow streams between 10…100% of the pipe diameter. The accuracy in partially filled pipes is <1% of full scale, and the accuracy in full pipes is <1% of the measured value. TIDALFLUX 2300 F does not require on-site calibration as it is wet-calibrated at factory in a direct comparison of volumes.
Due to the presence of H2S in many wastewater applications, the new TIDALFLUX 2300 F features an ATEX zone 1 approval. Here, the in-line flowmeter is a closed measurement solution for a safe and clean working environment, replacing open channel measurements. In addition to creating a toxic and explosive atmosphere, H2S presents another problem especially for partially filled electromagnetic flowmeters: their electrodes may have only a very short life span when in contact with the strongly corrosive H2S. The electrodes of the TIDALFLUX 2300 F are mounted at a height of 10 % from the pipe bottom, ensuring that they are always wetted to avoid corrosion. The capacitive level sensors are integrated in the liner and have no contact with the medium. Therefore they are unaffected by H2S and any residues that may be floating on the water surface (fat, oil, etc.) or particles in the water.
Although municipal or industrial wastewater transport is its main area of application, TIDALFLUX 2300 F can also be used for measurement of effluent brine from dredging, mining or sea/well water injection applications. Ranging from diameters DN200…1600 / 8…64", the measuring tube of TIDALFLUX 2300 F comes with a polyurethane liner which is resistant to abrasion that may be caused by particles such as sand and stones suspended in the brine. It also features a high chemical resistance and minimises the need for regular cleaning as its smooth surface prevents build up of fat and other deposits.
TIDALFLUX 2300 F is available with IFC 300 F (PF) remote converter in field housing. This means that the extended diagnostic functions of IFC 300, including application and device diagnostic as well as out-of-spec test, are now available for TIDALFLUX. For subsoil installation or applications in areas that can be partially flooded, TIDALFLUX 2300 F can be ordered as a protection rating IP68 version with special coating.
