Only the impeller operates in the wet chamber to prevent faults due to sediment. The roller counter is dustproof and condensation-proof and can be rotated for easier reading. The built-in pulse transmitter is cast in a waterproof enclosure and is easily replaceable. The meters are equipped with a sealed shield for protection against magnetic interference. The pulse transmitter for volume measuring components is fitted with a 100 , 1/4 W protective resistor (cable length 3 m) The compact design in subassemblies simplifies maintenance and repair. NOTE HYDROMETER contact water meter models 413 and 414 can be supplied calibrated on request. The meter is tested for compliance with the figures specified in the calibration regulations.
