Description
Seametrics EX150/EX250 Insertion Magmeters
Seametrics EX150/EX250 Insertion Magmeters has no rotor to stop turning in dirty water and there are no bearings to wear out. Like all magmeters, when used in chemical injection applications, these meters should be installed upstream of the chemical line (or far enough downstream to allow complete mixing of fluids before the meter). Adapters mate with standard 1-1/2” (11x/21x) or 2” (15x/25x) FNPT threaded fittings such as saddles and weldolets which may be purchased either locally or from Seametrics.
Seametrics EX150/EX250 Insertion Magmeters a rapidly reversing magnetic field is produced in the lower housing. As the fluid moves through this field, a voltage is generated that is measured and translated into a frequency signal proportional to flow rate. This square wave signal can be sent directly to a PLC or other control or can be converted using any of the Seametrics family of indicators and converters.
A modular system of electronics can be installed directly on the flow sensor or mounted remotely. The FT430 (externally powered with pulse) and the FT440 (loop powered), both provide digital rate and total displays, as well as a programmable pulse; the FT440 also provides a 4-20 mA analog output.
Seametrics EX150/EX250 Insertion Magmeters Advantages
Zero-Downtime Serviceability: The probe can be retracted into the valve body and isolated for cleaning or recalibration without shutting down main pumps or draining lines.
No Moving Parts: Eliminates rotor binding or mechanical fatigue caused by rust, grit, or suspended solids in raw water lines.
Flexible Transmitter Pairing: Interfaces with Seametrics wall-mount or meter-mount displays (e.g., FT430, FT440, or DL76) for 4–20mA output, Modbus RTU, pulse output, or data logging.
