The Marsh Multi-Mag flowmeter delivers accuracy in tough municipal and industrial water applications, being suitable for potable water, chilled water, raw water and even water containing sand and grit
Stormwater flowmeter delivers high accuracy
Engineers responsible for pollution and flood control will find the Marsh Multi-Mag flowmeter a reliable, scalable and economical solution to measuring the highly variable flows of stormwater run-off
Featuring an advanced insertable electromagnetic averaging design, the Multi-Mag measures volumetric flow with accuracy up to +/-1% of reading (from 0 to 20 feet/second + zero stability) and repeatability at 0.20 percent of the flow range.
The Multi-Mag flowmeter is especially well suited for early water treatment stages, such as flocculation, sedimentation removal and filtering operations: the rugged Multi-Mag is unaffected by the presence of sand and grit in converting raw ground water to potable drinking water.
It constantly profiles the water flow, ensuring unsurpassed accuracy, control and efficiency in processes designed to remove large particulates and clarify water prior to disinfection.

Additional benefits include a high turndown ratio, automatic sensing and correction for shifting profiles, and reduced operating costs due to its significantly lower energy requirements compared to most flowmeters.
The Multi-Mag flowmeter features a 4-20mA analogue output that is galvanically isolated and fully programmable for zero and full scale.
It is designed with dual alarms (2 separate outputs) and is fully programmable for high/low flow rates, percent of range, empty pipe, forward/reverse, polarity (normally opened/closed) and more.
Process and plant engineers find this flowmeter installs in minutes without shutting down the system and removes easily through standard valves.
Its rugged transmitter enclosure is NEMA 4X/IP65 approved for harsh operating environments.
Separate termination and electronics compartments are provided for superior reliability and safety.
A clear window is available for local field readings and inspection.
The Multi-Mag single-probe design is constructed with multiple sensors.
They constantly measure shifting flow profiles and compensate for variable flow rates (unlike single-point meters) to provide highly accurate measurement.
This advanced design is also suitable for use within close proximity to valves and elbows, which frequently cause flow profile disturbances that affect the accuracy of many other flow sensing technologies.
After years of extensive testing and thousands of installations worldwide, the Multi-Mag flowmeter provides multiple measuring points precisely positioned according to pipe size to make it the most accurate flowmeter available.
It is a viable option in many installations as a replacement for expensive spool-piece mag meters, turbine meters and other insertable flowmeters.
