1. Introduction

DBM610 airflow meter allows control and balancing of airflow in air conditioning system. Thanks to the interchangeable

hoods, the airflow can be used on any type of grids or diffusers in air supply or exhaust.

Easy to handle, lightweight, it allows accurate, sturdy and fast measurements.

t is supplied in standard with a 610 x 610 mm hood. Four other dimensions are available as options:

•1020 x 1020 mm

•720 x 720 mm

•720 x 1320 mm

•420 x 1520 mm

These hoods are airtight and have a transparent part on each side, allowing the user to see through the vent and

ensure that the hood is in a good position. The rods, made of fibreglass, provide a sturdiness of hoods.

The measurement grid, attached to the base, allows the measurement through 48 points all over the surface of the

grid. Measurement is performed using a differential pressure sensor, calibrated and compensated in atmospheric

pressure and temperature.

The measuring unit of the airflow meter, removable, can be used as a micromanometer

Real addition to airflow measurement, this instrument allows, by connecting a Pitot tube, to measure airflow velocity in air

duct or, by connecting two silicone tubes, to check filter fouling of air station. t is also possible to connect the matrix grid

designed for air velocity measurements on any types of large celling vent or diffuser. This grid calculates the average air

velocity from 24 points to guarantee a reliable measurement.

2.2. Grid

The measurement grid is fixed to the base in 6 points and is made up of the following elements:

•two chambers (for total pressure and for static pressure)

•2 pressure connectors

The measurement grid allows to measure differential pressure. t takes into account atmospheric pressure and temperature

compensation and works automatically in supply or exhaust.

2.3. Electronic housing

Features:

•Shock-proof made of ABS

•P54 protection

•Large graphic back-lighted LCD (86 x 51 mm)

•Auto shut-off adjustable from 0 to 120 min

•Manual or automatic autozero

•Removable housing for micromanometer function

•4 magnets at the back allow the mounting on the base (airflow meter mode)

•2 pressure plugs allow to set the housing on the base and the connection of silicone tube for the measurement with

a Pitot tube

•1 thermocouple plug on the top of the housing (micromanometer mode)

3.2. etting of the cloth

Before set the cloth on the frame, frame must be mounted.

➢First, insert a corner of the frame inside a corner of the cloth.

➢nsert the opposite corner of the frame in the corresponding corner of the cloth.

The colour mark must be in the middle of the frame side. (1).

➢Press on the corresponding side of the cloth to put it in the rail of the frame.

➢Proceed the same way for the rest of the cloth.

When the cloth is fixed on the frame:

➢Place the cloth on the base.

The mark on the cloth and the Velcro tape are opposed to the carrying handle of the base.

➢Put the elastic of the cloth around the DBM base.

➢Tighten the Velcro tape of the cloth on the base.

➢f necessary, turn the cloth to match the mark of the cloth with the mark on the base.
