Hygienic flowmeters

The HygienicMaster range of flowmeters is targeted primarily at the food and beverage, pharmaceutical and biotechnology industries. The range provides accurate measurement in hygienic applications ranging from water through to fluids with extreme viscosities, high solid concentrations or low conductivity. HygienicMaster is available in sizes DN 3 to 100 and is manufactured from FDA-approved materials and certified in accordance with EHEDG and 3A hygienic requirements.

Key features include a wide range of process connections; electrodes that are embedded into the liner to ensure a smooth surface without any sharp edges, minimising the risk of contamination; a sensor that is fully CIP/SIP cleanable; and a reinforced PFA liner which improves vacuum stability and prevents liner deformation, prolonging the meter’s operational life.

The backlit, graphical display can be manually rotated through 270°. The use of capacitive sensor technology also allows ‘through-the-glass’ data entry, enabling users to input or interrogate data for all parameters without removing the transmitter cover.

The HygienicMaster uses ABB’s universal HMI, using a four-button keypad and soft key technology, so that operators can easily scroll through and select options, while standard HART protocol enables online modification and monitoring of parameters.

A common electronics cartridge is used across all versions of the HygienicMaster, simplifying installation and reducing spare part costs and inventory, and a Gore-Tex membrane has been included in both the sensor and the transmitter. This membrane eliminates the risk of moisture ingress and condensation in humid environments or areas with large temperature fluctuations, which could potentially cause drift and measurement inaccuracy or even product failure.
