Description

ISM 5.0 Insertion Magmeter
The 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 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. 

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.

No Onsite Calibration Required

Based on your pipe type and size, liquid and flow rate each ISM 5.0 Insertion Magmeter is shipped from our factory configured for your application and ready to install. Connect the isolated 4-20mA output to control system or remote display, or use the relay pulse output.

How It Works

The ISM 5.0 Insertion Magmeter operates based on Faraday’s Law of electromagnetic induction: as flow velocity of a liquid increases through the magnetic field generated by the sensor head of the ISM flow meter, electrodes measure the voltage increase to accurately calculate flow. Four electrodes measure the induced voltage on opposite sides of the sensor. The voltage readings are sampled and averaged.

The ISM 5.0 Insertion Magmeter measures flow of electrically conductive liquids (20 µS/cm or greater) in full pipes. For proper measurement on plastic pipes the electromagnetic flow meter requires electrical grounding by connection to grounding rings or ground probes inserted into the pipe. Readings are not affected by the fluid temperature, pressure or viscosity.
