EX Protection ATEX 100a
Transducer types are available with an Ex-protected design, :
l ATEX Zone1: II 2G Ex ia IIC T4
l ATEX Zone2: II3G Ex nA IIC T4
When used with power supply and zener barrier the gear flow meters can be operated safely within Ex zone 1 or 2. Contact sales for further information.
Installation guidance
All hydraulic connections should be made by suitably qualified personnel. Inlet and outlet connections should always have a similar bore
size to that of the flow meter to prevent venturi or constriction effects.
l The flow meter should be connected using flexible hoses. The flexible hoses should be 'strain relieved' (clamped). Ensure the clamps
are at least one pipe diameter wide and positioned close to the fittings.
l Consideration should be given to the effects of cavitation erosion as this could damage the unit.
l Although the unit is bi-directional greater accuracy is achieved by ensuring the flow is passed in the calibrated direction shown on the
engraving by the larger arrow head.
l Care should be taken to ensure that the flow block is installed in a position which is not subjected to excessive fluid pulsation as this
can cause incorrect readings.
l Check IP rating before installing in wet areas. If installed in wet areas use a M12 cap to protect connector when no cable is present. IP
rating only applies if unit is fully connected.
l The flow meter can be mounted in any orientation.
l It is recommended that a 50 micron filter is installed in the hydraulic circuit prior to the flow meter. For heavy-duty applications, for
example installation close to a piston pump, or for advice on installation please consult the sales office.
l It is recommended that the pre-installed male-male fittings are not removed. If they are removed only the correct assembly torque must
be applied.
