Easy installation and handling
Differential pressure flow meters are used in many technical applications. As primary flow elements, orifice plates represent the most common solution. Orifice plates are notable for their easy installation and management.

The differential pressure generated by the primary flow element is normally transformed into an electrical signal proportional to the flow rate by a differential pressure transmitter.

High accuracy
Differential pressure flow meters are used in many industrial applications. If a high measurement accuracy is requested, the best solution for primary elements is a meter run.

High pressure recovery and low upstream and downstream requirements
Venturi tubes are reliable, easy to use and low-maintenance Venturi tubes are particularly suitable for the measurement of clean liquids and gases.

The main advantages of a Venturi tube over other differential pressure flow meters are the higher pressure recovery and the lower upstream and downstream pipe requirements.

Our FloTec pitot tubes are used for measuring flow according to the differential pressure principle. The volumetric flow is calculated from the difference between the static pressure and the dynamic pressure using Bernoulli’s principle and taking into account the pipe inner diameter. Using four dynamic ports this instrument is able to evaluate a better velocity profile inside the pipe. This ensures a higher accuracy in the measurement.
