MIS - Economical Full-Bore Magnetic Flow Meter - Flange - for Liquids

The KOBOLD MIS is an economical, full-bore magnetic flow meter that measures, monitors, and batches conductive liquids in 2 to 8 inch flanged pipelines. Also called an electromagnetic flow meter or a magnetic inductive flowmeter, it operates on Faraday's Law, covers flow rates from 2 GPM to 4,400 GPM, and pairs an obstruction-free flow tube with two configurable outputs, standard IO-Link communication, and a rotatable color display.

Designed for water treatment, wastewater processing, filtration systems, and general industrial applications, the MIS combines monitoring, transmitter, and batching functions in a single device. Because measurement is electromagnetic, readings are unaffected by fluid density, viscosity, or temperature variations.

Flow Ranges and Pipe Sizes

Five ANSI Class 150 flange sizes cover 2, 3, 4, 6, and 8 inch pipelines, with measuring spans reaching from 2...277 GPM in the smallest size up to 18...4,400 GPM in the largest. According to specifications, the full-bore design produces a maximum pressure drop of only 0.36 PSI at a flow velocity of 9.8 ft/s. Installation in pipes with larger nominal sizes is also possible using pipe tapers, with the resulting pressure loss taken into consideration.

Accuracy and Measurement Stability

According to specifications, the MIS delivers accuracy of ±(0.5% of reading + 0.5% of full scale) with repeatability of ±0.2% of full scale and a response time under 250 ms. Media viscosities up to 70 cP are within its ratings, the required minimum conductivity is 20 µS/cm, and built-in empty pipe detection recognizes a line that is not completely filled. Minor deposits on the measuring tube generally do not affect measuring accuracy unless their conductivity deviates significantly from the liquid.

Construction and Environmental Ratings

A powder-coated aluminum housing rated IP67 suits washdown environments. The MIS handles media temperatures from 14°F to 158°F, ambient temperatures from 14°F to 140°F, and line pressures up to 232 PSIG. Standard construction includes an NBR liner and Hastelloy C276 electrodes for broad compatibility with conductive process liquids. Installed weights range from 21 lb for the 2 inch meter to 107 lb for the 8 inch version.

U-PACE Electronics, Outputs, and IO-Link

The universal U-PACE electronics provide two arbitrarily configurable outputs, selectable as 4-20 mA, 0-20 mA, 0-10 VDC, or 2-10 VDC analog signals, or as switching, pulse, or frequency outputs. IO-Link V1.1 communication is standard. A 1.4 inch color TFT display rotates in 90-degree increments, refreshes at an adjustable 0.5 to 10 second rate, and is operated through four optical touch keys that work with gloves.

Batching and Bidirectional Totalization

An integrated batching function enables precise dispensing with external PLC control, so simple filling tasks run without a separate batch controller feeding the display's intuitive setup menu. Bidirectional measurement supports lines where flow reverses, and grand and resettable totalizers track volume with the flow rate, daily volume, and total volume shown in the units of measurement the operator selects.

Magnetic Flow Meter Applications

The MIS is designed for water tapping and water treatment, water distribution networks with leakage detection management, wastewater treatment, and filtration systems such as reverse osmosis and ultrafiltration, alongside general industrial applications. It is easy to commission via a clear guided menu and is available with quick delivery. For highly soiled fluids, a bypass pipe with a blind flange lets the line be cleaned without dismounting the flowmeter.
