Flow meter selection

Which flowmeters require temperature and pressure compensation? Do Anubis flowmeters need such compensation, and what are their advantages over orifice plate flowmeters?
Flowmeters that require accurate measurement of gas flow generally need temperature and pressure compensation.

Gas flow rate needs to be measured, as it must be converted to volume under standard conditions; since gas volume is affected by temperature and pressure, compensation is required. Saturated steam does not require compensation. Both Annubar and orifice plates operate on the principle of differential pressure; under different operating conditions, compensation may be necessary depending on the measurement requirements, which depends on the object being measured. The greatest advantage of orifice plates is their low pressure loss.
Both the Aniuoba flow meter and the orifice plate flow meter belong to the differential pressure type of flow meters; when measuring compressible gases, temperature and pressure compensation is required. The Aniuoba flow meter has low pressure loss, but it is prone to clogging, while the orifice plate flow meter has mature technology but high pressure loss.
Ainuba doesn’t require compensation, right? The transmitter that comes with Ainuba has a built-in temperature and pressure compensation module; the instrument outputs a compensated 4-20 mA Hart flow signal directly. Pressure compensation is built into the instrument itself, while temperature compensation is provided by the temperature sensor, which is integrated within Ainuba
If the flow meter is used for trade handover, the initial Coriolis mass flow meter does not require temperature and pressure compensation; all others do. Aniuba operates on differential pressure and also requires temperature and pressure compensation; the pressure difference is smaller than that of orifice plates.
