PROBES FOR FLUID VELOCITY MEASUREMENTS EV100 SERIES

A wide range of standard Pitot and directional probes for velocity measurements is available.

EV110The standard range comprises :

- Pitot tubes

- Directional anemometrics probes (Yaw-meters)

Special purpose probes can be designed and manufactured on request. Details should be supplied on the required geometry, dimensions, materials, operating temperature, etc.

 

1. DIRECTIONAL PROBES / YAW METERS :

The standard probes can be supplied in a straight or swan-neck form, in the following versions:

3 pressure orifices. Total head, and left and right hand orifices for determining the direction of the flow in a plane perpendicular to the probe body. Ref. EV130.

4 pressure orifices. 3 located as above, with an additional static pressure orifice. Ref. EV140.

5 pressure orifices. Total head, left, right, up and down orifices . This arragement makes it possible to measure the flow in two perpendicular planes. Ref. EV150.

EV130 and EV140 can be fitted with a shielded thermocouple (ref. EV132 and EV142).

 

Standard probe dimensions :

Diameter of probe body: 8 mm

Diameter of pressure orifices: 0.6 mm

Yaw angle range: ± 20°

Length of stem: 400 mm

Max. operating temperature: 200°C

Material: stainless steel

 

Probe tip dimensions, mm :

- EV130 : 6 x 3

- EV132 : 6 x 5

- EV140 : 6 x 4

- EV142 : 6 x 6

- EV150 : 9 (stem 10)

The probes can be used in fluids with solids in suspensions. They can be connected to all types of pressure and temperature transducers.

 

2. PITOT TUBES :

These are generally supplied with a stem at right angles to the head, but can be supplied as straight cylindrical tubes.

 

Standard Pitot tubes dimensions :

Diameter of probe head: 2.5 mm

Max. operating temperature: 200°C

Material : stainless

 

Length before elbow, in mm :

- EV110 : 0

- EV112 : 50

- EV120 : 80

 

Length after elbow, in mm :

- EV110 : 120

- EV112 : 120
