Pressure Manometer with Pitot Tube PVM 620
pressure manometer with high accuracy, data logging function and software

The pressure manometer with Pitot tube PVM-620 is a robust, compact and comprehensive meter to take measurements of pressure, air flow velocity and flow. The pressure manometer with  Pitot tube PVM-620 can be used with Pitot tubes to measure velocity and calculate flow, if the the surface of the channel or diameter has been previously programmed into the device. Thanks to its properties, the pressure manometer with  Pitot tube PVM-620 is ideal for installers, environment working staff, commissioning, monitoring processes and controlling systems. The following link has an overview where you will find pressure manometer most suitable to your needs.

Pressure manometer with Pitot tube PVM-620 

The most important advantages of the pressure manometer are:

-  Differential and static pressure measurement  from -3735 to +3735 Pa 

- Calculation and display of velocity through the differential pressure (only in connection with a pitot tube)

- Memorization of specific values

- Direct indication of the flow after entering the channel measurements

- Value memory with date and time

-  LogDat2 software and calibration certificate  included 

- Possibility of introducing a correction factor

- Pressure or flow

You can switch the display measurement values from pressure to air flow when using a Pitot tube or any other dynamic pressure sensor. After entering the area of the section you can also switch to flow.

- Outline the functionality principle  according to Prandtl

Dynamic pressure "q" measurement as the difference between the total pressure "pges" and the environmental static pressure "p".
This principle is used especially if the air to be measured has a flow velocity and a very high temperature.
The stagnation tube is an essential tool for determining the flow rate of air or gas pipes or air ducts. It is the combination of a Pitot tube to measure total pressure and a probe to determine the static pressure.

Pitot tube according to Pandtl

Air flow velocity

With the help of a Prandtl tube, you can measure the velocity of air flow in m / s. The air flow rate can be measured with a resolution of 0.1 m / s. In the pressure meter PVM-620,  the total pressure Pitot tube is hooked to the connector of high pressure and the static pressure tap to the low pressure connector. Before making any measurements,  you must perform a device reset. Then the catheter is inserted with the tip in the opposite direction to the flow of gas or air and as parallel as possible to the duct, and then you can read the measured values. The velocity of the current air flow is calculated automatically. The air density in turn depends on atmospheric pressure and current temperature. Through the Pitot factor,  the geometry of the Pitot tube  used is taken into account. It can be adjusted, and for the Pitot tube is 1.00.

Pitot Tubes
You can get Pitot tubes in stainless steel. We offer three different versions. The model with a length of 305 mm fits perfectly in the case of the pressure meter PVM-620. The elliptical shape of the head of the Pitot tube has the advantage that it reduces the measurement error caused by the different angles of flow during the measurement.
