10D1476 K-MAG MAGNETIC FLOWMETER INSTRUCTION MANUAL
This flowmeter can be used to meter either clean or dirty liquids. The meter may be used without
regard to the heterogeneous consistency of the measured liquid and is as independent of the
tendency to plug or foul as the pipeline in which it is mounted. By design, only the ceramic spool
meter body and electrodes are wetted parts, and will accommodate most acids, bases, water and
aqueous solutions.
Viscosity and density of the metered liquid have no effect on the measurement accuracy of the meter
and, therefore, signal compensation is not required. Metering limitations are confined to a minimum
threshold of electrical conductivity inherent to the liquid being metered. The degree of liquid conduc-
tivity has no effect upon the metering accuracy (as long as it is greater than the minimum level). The
liquid temperature and pressure are limited to the meter material specification limits. Refer to Section
1.3.
The meter body is a sealed section that bolts between the customer's pipe line flanges. The
measuring electrodes that contact the process liquid have their ends flush with the inside of the meter
tube. For accurate results, the meter bore diameter must be centered in the pipeline. For the larger
size meters, spacer sleeves are slipped over the flange mounting bolts. The smaller size meters use
a unique centering device to center the meter. The centering device is shown in Figure 1-1.
