LAISON’s electromagnetic flowmeters, adopting Faraday’s law of electromagnetic induction, are renowned for their accuracy and dependability in measuring conductive fluids.

These state-of-the-art devices are characterized by no moving parts, maintenance-free and strong anti-interference capabilities.

Available in a broad range of nominal diameters from DN100 to DN1200, LAISON’s flowmeters are the go-to solution for a multitude of industries, including petroleum, chemicals, steel, food processing, power generation, papermaking, water treatment, water supply, heating, and environmental protection.

To meet the diverse demands of different projects, LAISON offers two types of electromagnetic flowmeters: flange-mounted and insertion types. The flange-mounted type can be tailored with a variety of linings and electrode materials that are resistant to corrosion and abrasion, making them suitable for a wide array of fluid measurements.

The insertion type, on the other hand, provides the advantage of flexibility for existing pipe networks, enabling installation and removal without the need to shut down the water supply, thereby cutting initial costs and installation fees.

Both types are designed to operate on either battery power or mains electricity, ensuring they can be used in a variety of operational environments.

Flange-mounted TypeVelocity range: 0－10m/sAccuracy: ±0.5%R，±1%R（＜DN20 )Medium conductivity: ≥5uS/cm，Actual conductivity≥30uS/cmNominal pressure: 1.0 ~ 4.0MPaOutput signal: 4-20mA；Pulse/Frequency 2kHz(Default)，5KHz(Max)Communication: RS-485,Support standard Modbus-RTU protocol; GPRSPower Supply: 110/220VAC(100-240VAC)，50Hz/60Hz；24VDC ±10%Level of protection: IP65/IP68

Insertion Type

Velocity range: 0－10m/sAccuracy: v>1m/s, the measurement accuracy is ±1.5%; 0.1m/s<v≤1m s,the measurement accuracy is ±2.5%Medium conductivity: ≥30µS/cmNominal pressure: 0.6MPa、1.0MPa、1.6MPa (Maximum customizable4.0MPa)Output signal: 4-20mA；Pulse/Frequency 2kHz(Default)，5KHz(Max)Communication: RS-485,Support standard Modbus-RTU protocol, HART protocol; GPRSPower Supply: 110/220VAC(100-240VAC)，50Hz/60Hz；24VDC ±10%Level of protection: IP65/IP67/IP68

These flowmeters are often utilized for monitoring flow in pipelines and for billing commercial water consumption. They provide highly accurate measurements and are equipped to support a range of signal outputs, including pulse and analog current signals, as well as wireless and wired communication options such as RS-485 and GPRS. This versatility makes them an excellent choice for integration into remote monitoring and control systems, thereby boosting operational efficiency.

A prime example of their effectiveness is LAISON’s recent pilot project in the Democratic Republic of Congo, where electromagnetic flowmeters were instrumental in monitoring urban pipeline networks. This project represents a significant step forward in LAISON’s efforts to expand smart metering solutions in Africa.
