VD 500 Flow Meter

The integrated, precise differential pressure sensor measures the differential pressure/ dynamic pressure at the sensor tip. The pressure depends on the respective gas velocity. The flow is therefore easy to determine by the pipe diameter. The additional measurement of temperature and absolute pressure, and calculation of the relevant density means that measuring can be carried out for various gases, a wide variety of temperatures and pressures.

• Particularly suitable for extremely high flow rates
• Extremely fast response time: 100 ms
• Measures flow, total consumption, temperature and pressure
• Measurement at high temperatures – max. 200 °C
• Measurement in various gases by selecting gas type, on request
• Can be used in pipes from DN 20 to DN 500
• Installation via 1/2″ ball valve under pressure
• RS 485 interface (Modbus-RTU), 4…20 mA, pulse output as standard
