Foxboro 2818-SEBA-NSA-G-Z Magnetic Flowtube — 2800 Series, 18 in, 2,900–24,000 GPM, Hastelloy C Electrodes, 120V/60Hz, New

The Foxboro 2818-SEBA-NSA-G-Z is a new, 18-inch (450 mm) flanged magnetic flowtube from the Foxboro 2800 Series, rated for 2,900 to 24,000 US GPM of electrically conductive liquid, with Hastelloy C electrodes, a maximum working pressure of 150 psi at 180°F, and AC coil power of 120V / 60Hz. One unit only is in stock at Mel Supply in Columbus, Kansas — available for free local pickup or freight shipment. List price was $27,000; our price is $9,998 and we will consider reasonable offers. This is the large-line-size 2800 Series flowtube (Foxboro / Schneider Electric, formerly Invensys Foxboro) built for municipal and industrial plants that cannot afford downtime on a main line. It is a flowtube (sensor) only — it pairs with a compatible Foxboro magnetic flow transmitter, which is not included. The data plate on this exact unit is photographed in this listing: it stamps model 2818-SEBA-NSA-G-Z, reference number 04440415, AC calibration at 120V / 60Hz, and Hastelloy "C" electrodes, so you can verify compatibility before you buy. Why plants buy this flowtube Exact, hard-to-find model: 2818-SEBA-NSA-G-Z — an 18-inch 2800 Series tube that is long out of regular distribution. If your plant was built around this tube, this is a drop-in spare or replacement with no re-engineering. New, never installed: still secured in its wooden shipping crate with flange covers in place, factory red instruction tag attached, and the data plate legible in our photos. Hastelloy C electrodes: stamped on the data plate — the electrode material plants specify for corrosive process liquids. Built for harsh, outdoor service: general-purpose weatherproof housing rated IEC IP65 / NEMA 4X in the manufacturer specification for this housing code (-G). High capacity: 2,900–24,000 GPM covers main-plant water, wastewater, and process lines in a single 18-inch tube. Documented calibration data: AC calibration factor 0.000347591 mV/GPM is stamped on the plate (phase band E, parallel coils, 8.0 A max) — the numbers your instrument shop needs to configure the transmitter. Only one available: when this unit sells, there is no restock. Surplus new stock like this is why it is priced $17,002 under the $27,000 list.

No. 04440415; ECEP11701; Cert Spec CS-E/CG-A Approximate weight About 475 lb for the flowtube; 682 lb shipping weight, crated Condition New — never installed, in its wooden shipping crate / original packaging Quantity available 1 unit only SKU MEL-ACT58680-SZM Model code, decoded 2818 = 18-inch nominal line size. -SE = 304 stainless steel tube construction. BA = ANSI Class 150 carbon-steel flanges. N = neoprene lining. A (final code position) = configured for 120V, 60Hz AC transmitter service. -G = general-purpose NEMA 4X weatherproof housing. -Z = ultrasonic electrode-cleaning transducer option. The data plate on this unit separately stamps the electrode material as Hastelloy C — always confirm the plate photos against your application, because coil drive power varies by transmitter and an incompatible pairing can damage the tube. What you need to run it A magnetic flowtube is the sensor half of a magmeter system. You will need a compatible Foxboro AC magnetic flow transmitter (E96-type service, 120V / 60Hz for this unit's calibration), signal and power cabling, and a full pipe of conductive liquid in service. This listing is for the flowtube only — no transmitter, cables, gaskets, or bolting are included. Straight-pipe practice for this series is at least 5 pipe diameters upstream and 3 downstream for best accuracy. Applications Municipal drinking-water and wastewater plants, water and wastewater treatment, chemical processing, pulp and paper, food and beverage process water, power-plant service water, and general industrial measurement of conductive liquids, slurries, and process water on 18-inch lines. Freight and local pickup Local pickup is free in Columbus, Kansas (Columbus Warehouse) — bring a suitable truck or trailer; the crated unit weighs about 682 lb. Freight is available: this unit ships secured in its wooden crate by freight carrier. Message us with your ZIP and whether delivery is to a commercial dock or a residence and we will arrange the freight option for your order. One unit only — no combined or repeat stock. Frequently asked questions What is the Foxboro 2818-SEBA-NSA-G-Z? It is an 18-inch flanged magnetic flowtube (electromagnetic flow sensor) from the Foxboro 2800 Series, model 2818-SEBA-NSA-G-Z. It measures the volumetric flow of conductive liquids at 2,900 to 24,000 GPM when paired with a compatible Foxboro magnetic flow transmitter. Is this Foxboro flowtube new or used? New. It has never been installed, is still in its wooden shipping crate with flange covers and the factory tag attached, and its data plate is shown in the listing photos. Is a transmitter included? No. This is the flowtube (sensor) only. Its data plate shows AC calibration for 120V / 60Hz service (8.0 A max, parallel coils, calibration factor 0.000347591 mV/GPM). Pair it with a compatible Foxboro AC magnetic transmitter and verify compatibility before ordering — coil drive excitation power varies by transmitter. What are the electrodes and lining? The data plate stamps the electrodes as Hastelloy "C". The model code specifies a neoprene lining, a 304 stainless steel tube, and ANSI Class 150 carbon-steel flanges. What pressure and temperature can it handle? The data plate maximum working pressure (MWP) is 150 psi at 180°F, which matches the manufacturer limits for an 18-inch, ANSI Class 150, neoprene-lined 2800 Series tube. How is it shipped, and can I pick it up instead? Yes — free local pickup in Columbus, KS, or freight shipment in its wooden crate (about 682 lb shipping weight). Contact us for a freight arrangement to your ZIP before or right after ordering. How many are available? One. This is a single new-surplus unit (SKU MEL-ACT58680-SZM, Ref. No. 04440415). Once it sells, the listing ends and there is no restock. Stock note: New, 1 unit, Mel Supply — Columbus Warehouse, Columbus, Kansas.
