The TERZ 94 electronic turbine meter is a flow meter which directly measures the flow rate of gases at measurement conditions. The flow rate measured and the volume are displayed on an electronic totaliser. The operating principle of the meter is based on velocity measurement using a turbine wheel. The gas flow passes the ring-shaped inlet section of the flow straightener and reaches the coaxially mounted turbine wheel, whose speed is proportional to the mean velocity of the gas flow within the scope of the measuring range. The speed of the turbine wheel is recorded inductively using non-contact measurement by a pulse-wire sensor and a permanent magnet. Due to the fact the signal frequency is directly picked up at the turbine wheel, the meter is also suitable for control applications.
Suitable for natural, non-aggressive and manufactured gases; nitrogen, carbon dioxide and propane; and other gases upon enquiry Integrating flow meter with a special counter indicating flowing gas volumes at prevailing pressure and temperature (m³ at measurement conditions)
