Installation

Locate the flowmeter in a sheltered position away from falling water. Ideally flexible tubes should be used to plumb the flowmeter in as care must be taken to ensure that the end fittings on the meter are not stressed during use. Ideally the meter should be installed with straight lengths of tube either side, 10 pipe diameters upstream and 5 downstream. Install the device well away from valves, regulators bends and other components that would cause excessive turbulence on the fluid entering or leaving the meter. If necessary use spacer blocks and mounting clips to raise the pipe work centre line 58mm above the surface. It is good practice to use upstream and downstream isolating full bore ball valves to facilitate easy meter installation or removal. If push-in 3/8” John Guest fittings are used clip the pipes to the mounting surface 300mm upstream and 150 downstream.

Mount the connection box, using suitable fixings, onto a rigid surface with the cable entry at the bottom. The mounting screw centres are shown in the diagram on the right. When the flowmeter is clipped in place have the terminal screws at the lower edge. Note the rubber strip covering the terminals on the meter will not seal if water is persistently present in this area. Ensure the meter is not pressure washed. The Atrato can easily be dismounted by inserting a screwdriver under the mounting clip and gently unclipping it to release the main body. The PG9 thread can be either connected to suitable flexible conduit or be fitted with the supplied cable gland.
