BRAND: Seametrics

Reliable Flow Measurement for Large Water Lines Without Process Shutdown

The Seametrics EX150/250 is a hot-tap adjustable-depth insertion electromagnetic flow meter designed for large water lines where shutdown is not practical. Its isolation valve allows installation or removal under pressure, making it ideal for municipal water, irrigation, industrial water, cooling systems, and other large-pipe applications.

The EX150 fits 3" to 10" pipe, while the EX250 fits 10" to 48" pipe. The meter extends only about 1/8 of the pipe diameter, helping reduce clogging from debris.

Features

  • Hot-tap design allows installation and removal under pressure

  • Ideal for applications where pipe shutdown is not an option

  • Adjustable-depth insertion design

  • No moving parts for low maintenance

  • EX150: for 3" to 10" pipe

  • EX250: for 10" to 48" pipe

  • Brass or 316 stainless steel construction available

  • Standard brass valve, stainless valve optional

  • Stainless version certified to NSF/ANSI 61

  • Compatible with displays, converters, data loggers, and 4–20 mA output options

Why Choose the Seametrics EX150/250?

Unlike mechanical flow meters, the EX150/250 has no rotor, bearings, or moving parts. This makes it especially useful in applications where dirty water, debris, or long-term maintenance are concerns. The hot-tap design also makes it practical for existing pipelines where cutting service is difficult or expensive.

For large pipe flow monitoring, the EX150/250 provides a practical balance of durability, serviceability, and integration flexibility.
