Overview

Features

KIMO has designed and manufactured the Debimo mesuring blades for use in all types of air flow systems. Debimo flow measuring blades, when correctly placed in an air flow, generate a differential pressure, the square root of which is proportional to the air flow.

Applications : air supply systems in laboratories, air conditioning systems, air flow test rigs, fume extraction and exhaust systems, vacuum cleaning systems.

15 standard lengths available, with other available on request

Technical

Materials Extruded aluminium, galvanized steel fixing bracket, stainless steel screws

Operating temperature 100°C(maximum 210°C on request)

Repeatability Better than 0,3%

Maximum pressure 2 bar static

Accuracy From 3 to 5% depending on the installation*

* Accuracy depends on the very low differential pressure device used. The blade factor (K ) is theoretical, and the final measure depends on the ductwork installation. KIMO recommends that after installation a site measurement is made, with an accurate anemometer, and the differential pressure device adjusted to the real flow value.

FAQs

Q

Why do the blades have a minimum flow rate of 3.0 m/s ?

A

To measure flow a differential pressure must be created across the blade, and most pieces of measuring instrumentation are not able to measure this accurately below 3.0 m/s.

Q

Can the blades be positioned in any duct ?

A

Within reason the airflow blades can be installed in all ductwork systems.  Care must be undertaken in corrosive situations to avoid mismatch in materials, and wherever possible they should be located away from bends and dampers to avoid turbulence.
