Greyline ISM 5.0 Insertion Magmeter

Greyline Flow Meter
Electromagnetic Flow Meter
Insertion Flow Meter

Accurate, Low Cost Alternative to Full-bore Magnetic Flow Meters

Measure flow of water and conductive liquids in full pipes from 3 to 72″ (80 to 1800 mm) diameter.

The ISM 5.0 Insertion Magmeter senses flow using a low maintenance electromagnetic design with no moving parts. The dual-electrode sensor and continuous auto-zero function provides high accuracy – even at low flow rates. State-of-the-art electronics and patented design features help maintain its NIST traceable accuracy over time.

The ISM 5.0 dual pair electrode sensor inserts through a tap in the pipe wall. It can be easily installed in new pipe systems or by hot tap in pressurized pipes with flowing liquids. There are no moving parts so obstruction to flow and pressure drop is minimal. Installation through a full port ball valve allows easy retraction and reinsertion without shutting down flow. The insertion depth is adjustable according to the pipe diameter and an insertion depth gauge is supplied with each flowmeter. The optional Installation Hardware Kit includes a branch outlet, close nipple and full port 1” isolation valve.

Use it for:

  • Potable Water
  • Water Distribution
  • Pumping Station
  • Irrigation Water
  • Treated Water
  • Reclaimed Water
  • Filter Balancing and Blackwash
