As done in literature , the gas velocity in the retort was measured through a thermal anemometer
equipped with a customized control device system.
This may be a pitot array or thermal anemometer
Tenders are invited for Supply Of 1) Testo-425 Or Equivalent Compact Thermal Anemometer
With Fixed Velocity Probe Including Temperature Measurement And Telescopic Handle,Batteries And Calibration Protocol Alongwith Ccessories As Per Ananexure-I, 2) Mextech Make (Model Ht6510a) Or Equivalent Shore Hardness Tester To Measure The Penetration Hardness Of Rubber,Elastomers And Other Rubber Like Substance Such As Neoprene,Silicone And Vinyl
It might also be desirable to augment the PIV measurements with thermal anemometer
measurements in the regions of higher velocity well above the patient, where a thermal anemometer
will still be relatively accurate, especially to investigate the turbulence levels.
The airflow sensor incorporates the same thermal anemometer
technology used by service technicians (certifiers) to annually verify a user's biological safety cabinet's airflow performance.
TOLLS & [ILLUSTRATION The Articulating Thermal Anemometer
A thermal anemometer
equipped with a customized control device system was adopted for the measurement of gas flow velocities in the retorting zone.
A multichannel low-velocity thermal anemometer
with omnidirectional velocity transducers was used to perform mean velocity, turbulence intensity, and air temperature measurements at several points in the room.
Multi-channel low velocity thermal anemometer
with five omni-directional velocity probes (SENSOR-ELECTRONIC HT-400) was used to perform measurements of velocity field in the personalized airflow.
Because the flow meter is not self-correcting for temperature and humidity as with an electronic thermal anemometer
, you will need to know the air temperature, humidity and barometric pressure.
Usually, a thermal anemometer
also includes a sensor for the fluid temperature and a bridge circuit to compensate for temperature variations.
At present, a thermal anemometer
with an omnidirectional velocity sensor is most often used in practice due to its low price and easy and convenient operation.
