Having been in business for over 50 years, McCrometer is currently a leading global flow instrumentation specialist developing innovative, high-quality, precision flow meters for the most demanding liquid, steam and gas measurement industry applications. McCrometer’s technologies produce high-performance products and ACG Technology Ltd. is proud to represent the Marsh Single-Mag Flow Meter and the Marsh Multi-Mag Insertable Electromagnetic Averaging Flow Meter; two of the most accurate, innovative and trusted flow meters on the market.
The Marsh Single-Mag Flow Meter is an insertion-type device that provides a highly cost-effective solution for the accurate measurement of liquid flow in closed conduit, pressurized pipe applications. Unlike conventional magnetic meters, the Single-Mag’s cost is independent of pipe size. Velocity and pipe diameter information are utilized by the Single-Mag to determine flow over wide flow ranges with a high degree of accuracy. The Marsh Single-Mag reliably measures flow in water and wastewater as well as any type of industrial flow processes involving conductive fluids such as potable water, slurries, sludge, cooling water, and pulp stock.
The Marsh Multi-Mag Insertable Electromagnetic Averaging Flow Meter is truly a revolutionary instrument with unprecedented accuracy, even in these most difficult flow conditions. It is ideal for measuring potable water, chilled water, raw water, water with sand and grit, and other debris-free water applications. After years of extensive testing and thousands of installations worldwide, the patented Marsh Multi-Mag Flow Meter provides multiple measuring points precisely positioned according to your pipe’s size to making this the most accurate flow meter available. Typical applications include: custody transfer, filter balancing, filter backwash, water treatment processes, and distribution management.
MARSH SINGLE-MAG FLOW METER
- Supports pressurized line sizes from 2 to 96 inches (50-2500 mm)
- Proven electromagnetic technology based on Faraday’s Law
