Seametrics iMAG4700 Electromagnetic Flow Meter

Fits conductive liquid flow in flanged pipe runs (2…12 in; 14 & 16 in with adapter kit) where you need a magmeter with pulse and optional 4–20 mA / Modbus, IP68 submersible rating, and NSF/ANSI 61 — battery or AC/DC powered by variant.

Key advantages

Flanged magmeter sizes — 2…12 in standard; 14 & 16 in with adapter kit; velocity to 10 m/s.
Reading accuracy options — ±0.75% of reading (4700p/4700r) or ±1.0% (4700).
Power choices — battery (4700); DC 9–36 V; AC 100–240 V (4700r/4700p).
IP68 / NSF — NEMA 6P continuous submersion; NSF/ANSI 61; CE; CSA/CUS.

Typical applications

Municipal and irrigation water metering in flanged lines.
Buried or flooded vaults needing IP68 continuous submersion.
Sites choosing battery vs DC/AC powered iMAG variants.

Selection guide

Pipe size / velocity — 2…12 in (14 & 16 in with adapter kit); max velocity to 10 m/s; low-flow cutoff 0.5% of max flow.
Accuracy — ±0.75% of reading (iMAG 4700p / 4700r); ±1.0% of reading (iMAG 4700); ±0.025% of full-scale flow from cutoff to 10 m/s.
Outputs — Pulse scaled (standard); 4–20 mA optional (std on 4700p); Modbus optional; Sensus Smart Output optional; high-speed digital optional.
Supply — Battery (4700); DC 9–36 Vdc @ 250 mA max / 30 mA avg; AC 100–240 Vac 50/60 Hz 0.12 A (4700r/4700p); battery backup options.
Process connection — Flanged (ANSI 150 lb pattern F1; US8 option); epoxy-coated welded steel body.
Wetted — Liner polyurethane/Noryl; electrodes 316SS standard / Hastelloy optional.
Pressure / media temp — 150 psi (10.3 bar) line pressure; operating 10 to 140 °F (−12 to 60 °C).
IP — IP68 / NEMA 6P / CSA 6P (10 ft / 3 m continuous submersion).

Common mistakes

Ordering base iMAG 4700 (±1.0% rdg) when the loop needs 4700p/4700r (±0.75% rdg) — accuracy is variant-dependent.
Assuming 4–20 mA is always included — pulse is standard; 4–20 mA is optional (standard on 4700p).
Exceeding 150 psi (10.3 bar) or media temperature outside 10…140 °F (−12…60 °C).
Specifying 14/16 in without the adapter kit path called out.
Leaving ambient blank on this page — ambient is not populated in checked data; confirm on datasheet if the site is extreme.

When to RFQ / what to tell us

Pipe size (2…12 in, or 14/16 in with adapter), fluid conductivity, and working flow / velocity.
Variant preference: 4700 / 4700p / 4700r (accuracy and power differ).
Outputs needed: pulse, 4–20 mA, Modbus, Sensus Smart Output, high-speed digital.
Supply: battery vs DC 9–36 V vs AC 100–240 V; backup yes/no.
Electrode material (316SS vs Hastelloy), meter-mounted vs remote display, quantity, ship-to country.

FAQ

Q: Which iMAG 4700 variant do I need? A: Accuracy and power differ: ±1.0% rdg on iMAG 4700 (battery); ±0.75% on 4700p/4700r with AC/DC options; 4–20 mA is standard on 4700p. State accuracy, power, and output needs in the RFQ.

Q: Is the fluid conductivity a requirement? A: Magmeters need a conductive liquid. Send fluid type and approximate conductivity with pipe size and flow so we can confirm fit.

Q: Which approvals apply? A: CE, NSF/ANSI 61, CSA/CUS per OEM published values. IP68 / NEMA 6P / CSA 6P covers continuous submersion to 10 ft / 3 m.

Q: What should I send for a quote? A: Pipe size, flow, variant, outputs, supply, electrode material, display mount, quantity. Compatible with systems using Seametrics iMAG4700 if you need a drop-in check — we do not claim authorized-dealer status.
