Delta-Elektrogas EQZ Quantometers

In industrial energy management, understanding exactly where and how gas is consumed is essential for cost reduction. The EQZ series operates on the turbine principle; as gas flows through the meter, it drives a turbine wheel at a speed proportional to the flow velocity. This rotation is then transmitted via a magnetic coupling to a mechanical index, providing a clear and tamper-proof reading of the total volume passed through the line.

The Delta-Elektrogas EQZ Quantometers are specifically engineered to provide a high degree of measurement repeatability even in fluctuating flow conditions. The specialized aerodynamic design of the flow straightener within the meter body minimizes turbulence, ensuring that the turbine wheel receives a stable gas stream. This leads to high accuracy across a wide turndown range. Furthermore, the meter is built with high-quality bearings and a rugged aluminum housing, ensuring a long maintenance-free service life. For facilities looking to integrate data into a Building Management System (BMS) or PLC, the EQZ series can be equipped with low-frequency pulse transmitters, allowing for remote monitoring of instantaneous and totalized flow data.
