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.
