Measuring system for ultra-sonic measuring of velocity and volume flow, especially for wet and aggressive smoke emissions (waste incineration)

Features

In-situ measuring method

Measurement possible below dew point and for high dust concentrations

Continuous measurement of normal volume flow and gas velocity

Automatic zero point and reference point control

Direct connection for temperature and pressure correction

Parameter input via keyboard or PC

Continuous temperature measuring

Applications

Volume flow measuring at low speeds

Plants with damp and/or aggressive exhaust gas, e.g. in waste incineration plants.

Volume flow measurement at high dust content
