U020-0028 | Flow | Mag | 12 in | PTFE | Grd Rng | Amp | Veris

Electromagnetic (mag) flow meters are capable of measuring flow in almost any liquid, slurry or paste with a minimum of electrical conductivity using Faraday's law of induction. These meters are highly accurate, at 0.25% or better, exceeding AWWA accuracy standards for mechanical meters. The smart, micro-processor based electronics are simple to operate, with AMR and SCADA ready standard outputs. The NEMA 4X enclosure provides durability.

• Reliable, durable design - open flow tube design, no head loss, no moving parts to fail
• 0.25% accuracy independent of fluid viscosity, density, and temperature
• Bi-directional flow measurement capability, suitable for inter-city billing
• Password security - protect against unwanted program changes
• Wide flow range - exceeds operating characteristics of turbine and propeller meters
• Works with most solids common in liquid systems, great for well water and reclaimed water systems, not fouled by sand, gravel, or debris
• Flow direction - uni-directional or bidirectional, two separate totalizers (programmable)
• Coil power - pulsed DC
• 4 to 20 mA, 0 to 20 mA, 0 to 10 mA, 2 to 10 mA (programmable and scalable); voltage sourced 24 VDC (isolated); maximum loop resistance less than 800 Ohm analog outputs
• Four total, configurable 24 VDC sourcing active output (up to two), 100 mA total, 50 mA each; sinking open collector output (up to four), 30 VDC maximum, 100 mA each; AC solid-state relay (up to two), 48 VAC, 500 mA maximum digital outputs
• Scalable up to 10 kHz, passive open collector up to 10 kHz, active switched 24 VDC, up to two outputs (forward and reverse) pulse width programmable from 1 to 1100 ms or 50% duty cycle pulse outputs
