Insertion Electromagnetic Flow Meter | Seametrics series EX100
The EX100/200-Series are adjustable depth insertion magnetic flow meters that fit 3” to 48” pipe (up to 72” optional). The complete lack of moving parts of the EX100/200-Series is the source of its reliability. Brass and stainless steel models withstand a variety of temperatures, pressure, and chemical conditions.
The EX-Series 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. 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 the 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 a 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. The AO55 is a blind analog (4-20 mA) transmitter. Programmable pulse for pump pacing is available with the PD10 (available as the wall-mounted unit only).
The “hot-tap” models (EX15x/25x) can be installed or serviced without shutting down the line by means of a 2” full-port isolation valve that comes with a nipple for installation on the pipe fitting; a bronze ball valve is standard, with a 316 stainless steel valve option if needed. In most circumstances, no special tool is required. Reverse flow output and immiscibility are optional.
