Single-Use Electromagnetic Flowmeter GENERAL The BIOMAG is an electromagnetic flowmeter designed for biopharmaceutical applications. The BM series flow tube made of polysulfone (PSU) resin has a single-use structure and can be easily replaced and sterilized with gamma rays. It can be attached to the BIOMAG4050C transmitter in a single operation, enabling stable flow measurement.

FEATURES

❏ Flow tube replaceable with one operation The single-use electromagnetic flowmeter adopts the easy- to-replace BM series flow tube and is available in five sizes from 1/4" to 1". ❏ Compact transmitter with high-performance system The BIOMAG4050C transmitter is available in three sizes from small (1/4"), medium (3/8" to 1/2") and large (3/4" to 1") and can output the measured flow rate as both analog and pulse signals. ❏ High accuracy The BIOMAG4050C transmitter combined with the BM series flow tube enables high accuracy of ±1% of reading with flow velocity tolerance of 0.001 m/s. ❏ Biocompatible material The flow tube (wetted part) is made of biocompatible polysulfone (PSU) which complies with USP Class VI, ISO10993, and can be sterilized with gamma rays up to 50 kGy. ❏ No need for field adjustment Readjustment is not required after replacing the flow tube. It is easy to use as a single-use device. MEASURING PRINCIPLE The measuring principle of an electromagnetic flow meter is based on Faraday’s law of electromagnetic induction. When a conductive liquid flows vertically through the magnetic field generated by an exciting coil, an electromotive force is induced between the electrode potentials in a mutually perpendicular direction. The electromotive force is proportional to the flow velocity and magnetic flux density, and thus the flow rate can be determined by detecting the electromotive force. U = v × k × B × D v = average velocity, k = correction coefficient, B = magnetic field strength, D = diameter of flow meter ① Exciting coil ② Magnetic field ③ Electrode ④ Electromotive force (proportional to velocity) TG-F2180-E02 3rd edition Sep 2023 K 1st edition Oct 2021 K
