deltaflow pitot tube

Averaging pitot tube
for flow metering of steam, gas and liquids.


deltaflow - avering pitot tube

The deltaflow averaging pitot tube is a cost- and energy efficient flowmeter for gases, liquids and steam.

Due to the special probe profile the deltaflow flow measurement can assure the highest level of precision and excellent process liability, even under extreme conditions. Averaging pitot tubes are causing the lowest pressure loss of all dp-flow meters and are therefore highly energy efficient. The deltaflow has been installed several ten thousand times in all industrial fields. Compared with traditional ISO 5167 primary elements such as orifices or venturis, deltaflow is not only saving energy but is also more inexpensive and causes less mounting costs. deltaflows high tolerance on non ideal flow profiles ensures high accuracies even under short inlet conditions.

Typical applications are flow measurement of steam, the metering of perssurized air, liquid flow measurements of water, oil, benzene. deltaflow is used to measure stack gas and flare gas, natural gas, bio gas and many more…

The deltaflow averaging pitot tubes are used in thousands of industrial plants such as power plants, sewage plants, breweries, automotive plants, steel plants… For the calculation and design the deltaflow flowmeter a self-explanatory software is free for your download.

deltaflow: the economic and ecologic flow meter solution

Compared with classical primary elements such as venturi, orifice or nozzle, the deltaflow is not only more accurate and reliable but saves also a huge amount of energy. Remembering that a single deltaflow in steam may save several kW of energy, one can imagine that deltaflow is not only saving money but also has an countable positive effect on the energy losses in industrial processes. This is not only economic but also reduces the world wide greenhouse effect.

deltaflow plus Multivariable SYS-MMF: This is an ultra compact, easy to use and inexpensive solution

Steam mass flow meter
Mass flow deltaflow with p&T-compensation, PN40
Order the deltaflow pitot tube together with the multivariable systec transmitter SYS-MMF.
SYS-MMF not only measures the differential pressure, but also the absolute pressure P1 and the process temperature via the integrated PT100,. The SYS-MMF then internally calculates the p&T compensated mass flow (or standard volume flow) for gases and steam. A differential pressure mass flow measurement could hardly be integrated in a simpler, more compact and cheaper way. The SYS-MMF outputs the measuring current signal directly via its 4..20mA output.
