FEATURES

nnnn

Models 413 and 414 are multi-jet impeller meters designed

nnnn

to the latest technical standards with completely dry running

nnnn

operation and magnetic coupling. Only the impeller operates

nnnn

in the wet chamber to prevent faults due to sediment.

nnnn

The roller counter is dustproof and condensation-proof and

nnnn

can be rotated for easier reading.

nnnn

The built-in pulse transmitter is cast in a waterproof enclosure

nnnn

and is easily replaceable. The meters are equipped with a

nnnn

sealed shield for protection against magnetic interference.

nnnn

The pulse transmitter for volume measuring components

nnnn

is fitted with a 100 Q, 74 W protective resistor (cable length 3 m)

nnnn

The compact design in subassemblies simplifies maintenance

nnnn

and repair.

nnnn

NOTE

nnnn

HYDROMETER contact water meter models 413 and 414 can

nnnn

be supplied calibrated on request. The meter is tested for

nnnn

compliance with the figures specified in the calibration

nnnn

regulations.
