Replies within 30 minutes during business hours (Mon–Sat, 10:00 AM – 6:30 PM IST). Assembled, tested and calibrated by Arrowmech in Surat, India — supplied pan-India and for export.
Zero wear, zero pressure loss, minimal maintenance over decades of operation.
DN15 to DN500 with flanged and sanitary connections for any pipe.
Water, slurries, acids, alkalis — any electrically conductive fluid.
4–20mA (isolated), RS485, and pulse standard — HART available on request. Built-in surge protector.
Forward and reverse flow across the full 0.2 – 12 m/s velocity range.
Flags an empty or partially filled pipe instead of reporting false flow.
Automatic 'zero' calibration and low flow cutoff, with a resettable totalizer.
m³, kg, or litres — per hour, minute, or second, selectable on the meter.
An electromagnetic flow meter generates a magnetic field across a non-magnetic pipe section. As conductive fluid passes through, it induces a voltage proportional to flow velocity — picked up by a pair of electrodes flush with the pipe wall. No obstruction in the flow path, no moving parts, no pressure drop.
Each AEFM-100 is wet-flow calibrated against traceable national standards before dispatch. The full-bore design tolerates abrasive slurries, aggressive chemicals, and CIP cleaning cycles. PTFE, PFA and rubber liner options cover virtually every process condition you'll encounter — from raw effluent to high-purity WFI.
Why the technology fits — engineering reasons, not marketing ones. All facts below are from the AEFM-100 datasheet.
The full-bore design has no obstruction to foul or clog, so raw sewage, industrial and domestic effluent pass with zero pressure drop. PTFE or rubber lining is standard, and electrode options from SS316L to Hastelloy C, Titanium, Tantalum and Platinum resist aggressive effluent chemistry — including acidic, alkaline and salt-laden streams such as brine and sea water, with the appropriate lining.
Bidirectional measurement across 0.2–12 m/s, empty-pipe detection, automatic zero and low-flow cutoff make the meter dependable for plant water balance — cooling circuits, heat exchangers, and supply headers where a false reading from a part-filled pipe is not acceptable.
Measures any conductive water from ≥10 µS/cm — borewell, raw and potable supplies — with DN15 to DN500 covering delivery lines end to end. Electromagnetic meters need a conductive medium: for DM or RO water, use the clamp-on AUFM-100 ultrasonic flow meter instead.
