Description
Description
APPLICATION  
  • ZVP probes are designed to measure air flow in air ducts.
  • Operating on the pitot tube principle, ZVP probes measure the total and static pressure values, which allows calculating air flow.
DESIGN  
  • The special profile of the probe neutralises the influence of back eddies, which can affect the static pressure measurement.
  • The precisely calculated number and positioning of the nozzles gives the highest possible accuracy of 98% already at 1 m/s.
  • The simple design makes it easy to install the probes yourself.
  • The sealed seat prevents air leaks.

ZVP probes operate on the pitot tube principle. The total pressure Ptotal is measured on one of the surfaces of the probe. The static pressure Pstat is measured on the opposite side. The difference between these pressures is velocity pressure Pvel, which is expressed by the following formula:

Pvel. = ½ x ρ x v2

Pvel. = velocity pressure in Pa

ρ – density of the gas (air) in kg/m3

v – velocity in m/s

Air volume can be determined with this formula:

Q = KV x √dP

Q – air volume in l/s

KV – KV value

dP – pressure difference measured by the ZVP probe in Pa
