Introduction:
JIRS FL‑8870 E‑mag C type electromagnetic flowmeter is a high‑precision industrial flow measuring instrument composed of sensor and converter, working based on Faraday’s law of electromagnetic induction. It measures volume flow of conductive liquid and slurry inside closed pipelines.
This model supports integrated round/square converter and separated remote‑mount converter. The LCD back‑light display shows instantaneous flow, flow velocity, forward & reverse total volume, difference totalizer, alarm status and empty‑pipe warning. Multiple lining, electrode, explosion‑proof grade and signal output options satisfy complicated working conditions of water treatment, chemical industry, mining and environmental‑protection projects.
Main Characteristics:
No obstruction inside measuring tube, no pressure loss, no moving parts, low maintenance cost, long service life.
High‑precision measurement: ±0.3% of reading (DN15‑DN600, velocity ≥1m/s); ±0.5% of reading (DN3‑DN10 / DN700‑DN3000, velocity ≥0.8m/s).
Supports bidirectional flow measurement: forward total, reversed total and total difference three‑group totalizer built‑in.
Rich material options for lining & electrode, adapt corrosive, abrasive medium such as acid, alkali, slurry, sewage.
Multiple converter options: round integrated, square integrated, square separated; button / magnetic button operation available.
Complete signal outputs: 4‑20mA analog, pulse/frequency, dual alarm relay, RS232 / RS485 / HART / Profibus‑DP digital communication.
Wide size coverage: nominal diameter DN3 ~ DN3000, nominal pressure 0.6‑6.3 MPa.
Protection grade IP65 / IP67 / IP68 available; explosion‑proof versions Exdibmb Ⅱ CT6 Gb / ExdibmbIIB+H2T6 Gb for hazardous area.
Self‑diagnosis function: empty‑pipe detection, fault alarm, test mode for system debugging.
Separated version can reach max 100 m distance between sensor and converter with special STT3200 cable.
