> Primary flow elements

Orifice plates, meter runs, flow and Venturi nozzles, Venturi tubes, pitot tubes and restriction orifices are part of our portfolio of primary flow elements. All our primary flow elements are designed in accordance with the principles and requirements of international standards (ISO 5167/ISO TR 15377, ASME MFC, ASME PTC6, BS 1042, DIN 19206, UNI 10023). We offer calibration certificates in accordance with the ASME PTC6, ISPESL and IBR standards.

> Digital pressure gauges

Flow switches are used for the display and monitoring of the flow of liquid and gaseous media. The instruments feature a high switching accuracy and functional safety, low switch hysteresis and continuous switch point setting by the operator.

The wide selection of WIKA flow switches also includes viscosity-compensated models and ATEX-certified instruments for use in hazardous environments.

> Air flow sensors

Air flow sensors are suitable for the measurement and control of air flows in ventilation and air-conditioning systems. The air flow calculation is made using the ventilator constant (k factor). For operation in ventilation pipes and ducts, air flow sensors are available with special measuring probes.
