Series C Meters Offers More

To eliminate restrictions for future upgrades Series C Meters are equipped with a hybrid magnetic coupling. Using a special designed magnet inside the meter, the reading of the meter can be changed from “mechanical” (magnet is used to drive the follower magnet of the mechanical index) to “electronic” (magnetic field orientation is used to activated pulse wires for detecting the rotation, direction and position of the impellers). The index and its functions can be exchanged with just “one twist and a click”.

This means that the most basic meter version is already prepared for upgrades to a fully sophisticated electronic meter including conversion (PTZ) and communication features (GSM, ISDN, PSTN, Ethernet, etc). From a standardization point of view, the couplings of the iMeter rotary meters series and the turbine meters series are similar, meaning that all the mechanical and electrical features are also similar, thus reducing inventory and increasing modular flexibility to its fullest extent.

The Series C Meter mechanical index contains a pocket that can hold different types of LF pick-ups such as reed switches, Wiegand sensors or fraud detection devices. This ability to change sensors quickly and easily, gives the meter maximum flexibility. The Mechanical index is 100% sealed to avoid condensation of the index.

Features

Series C Meters Design Features

• Unique shape of the meter body and impellers
• Design of the main shafts and its bearings
• Material selected for the meter body
• Overall dimensions of the meter

There is no bending, no twisting, no torque affect, and little vibration.

Series C Meters Advantages

• Lower product price.
• Lighter weight of the meter
• Smaller overall dimensions, allowing compact metering stations
• Reduced pressure drop due to the shape of the impellers.
• Lower total cost of ownership (TCO) by reducing the cost of maintenance.
• Reduced installation stresses due to the robust design of the meter body.
• Reduced vulnerability to overloading, gas impurities, and pressure shocks due to the robust design of the meter.
