MODMAG

MODMAG is a brand of electromagnetic flowmeters used for measuring the volumetric flow of conductive liquids in closed pipes. The product family covers inline magnetic flowmeters in a range of line sizes, with body materials including steel and sealing options such as natural rubber, PTFE, and EPDM. These meters operate on the Faraday induction principle: a conductive liquid moving through a magnetic field generates a voltage proportional to flow velocity, which the transmitter converts into a flow signal. MODMAG meters are available with accuracy specifications of ±0.2% or ±1.5%, depending on model, and provide either a 4-20 mA analog output or a standard frequency pulse output. Most models include an LCD or digital display for local indication. Maximum voltage is 240V AC. The meters are designed for universal mounting orientation, allowing installation in horizontal, vertical, or inclined pipe runs without reconfiguration. O-ring materials are selected to suit the measured fluid; natural rubber and EPDM are common for water, while PTFE offers broader chemical compatibility. Pipe sizes span from 1 inch to 12 inches in the models listed, covering small-batch dosing lines through to larger distribution headers. Typical applications include water treatment, cooling loops, process water, and other systems handling conductive liquids. Because the meters are inline devices, they install directly into the pipework and do not require straight upstream or downstream runs beyond the manufacturer's recommended minimums. 3G Electric supplies MODMAG inline magnetic flowmeters as part of its industrial equipment catalog. The line includes 13 SKUs at present, with specifications covering accuracy, output type, display, maximum voltage, pipe size, and O-ring material. Each product listing provides the manufacturer part number, key technical data, and logistics information. 3G Electric supports global procurement and shipping, allowing plant engineers, maintenance managers, and procurement specialists to source MODMAG meters alongside other industrial flow, burner, pump, and gas control equipment. For technical selection, buyers can reference the published accuracy class, output signal, and wetted-material data to match the meter to the process fluid and control system. The 4-20 mA output models integrate with standard PLC and DCS analog input cards, while frequency pulse output models suit totalizer or batch controller inputs. The digital or LCD display provides local flow rate indication without additional instrumentation. MODMAG meters are intended for conductive liquids; they are not suitable for non-conductive fluids such as hydrocarbons or deionized water without special electrodes. Installation requires a full pipe and a conductive fluid, and the meter body must be grounded to the process liquid to minimize measurement noise. The universal mounting orientation simplifies replacement of existing meters where piping geometry is fixed. 3G Electric's catalog includes the MPN and SKU for each MODMAG meter, enabling cross-reference against existing bills of materials. The product data covers pipe sizes from 1 inch to 12 inches, with additional sizes available across the full 13-SKU range. Accuracy classes of ±0.2% and ±1.5% allow selection based on the required measurement uncertainty for the application. Output options include 4-20 mA and standard frequency pulse, and display options include LCD and digital. Maximum voltage is 240V AC across the listed models. O-ring materials include natural rubber, PTFE, and EPDM, with selection driven by fluid compatibility and temperature. 3G Electric provides global shipping and logistics support for MODMAG meters, with product specifications and MPNs published for each SKU to assist with technical evaluation and procurement.

Frequently asked questions

Common questions about MODMAG from 3G Electric.

What is the accuracy of MODMAG inline magnetic flowmeters?

MODMAG inline magnetic flowmeters are available with accuracy specifications of ±0.2% or ±1.5%, depending on the model. The ±0.2% models are typically used where tighter flow measurement is required, such as process water or cooling loops. The ±1.5% models are suited to applications where a broader tolerance is acceptable. Accuracy is stated under reference conditions; actual performance depends on installation, fluid conductivity, and grounding. Each product listing on 3G Electric states the accuracy class for that specific SKU.

What output signals do MODMAG electromagnetic flow meters provide?

MODMAG electromagnetic flow meters provide either a 4-20 mA analog output or a standard frequency pulse output. The 4-20 mA output is used for continuous flow rate transmission to PLC or DCS analog inputs. The frequency pulse output is used for totalizing or batch control, where each pulse represents a defined volume. Both output types are available across the MODMAG range. The product listing for each SKU specifies the output type. Maximum voltage for the listed models is 240V AC.

What pipe sizes are available for MODMAG inline flowmeters?

MODMAG inline magnetic flowmeters are available for pipe sizes from 1 inch to 12 inches in the models listed by 3G Electric. The full range includes 13 SKUs, with additional sizes potentially available. The meter is selected to match the nominal pipe diameter. Installation requires a full pipe and a conductive liquid. The universal mounting orientation allows the meter to be installed in horizontal, vertical, or inclined pipe runs. Each product listing states the pipe size for that SKU.

What O-ring materials are used in MODMAG flowmeters?

MODMAG flowmeters use O-ring materials including natural rubber, PTFE, and EPDM. The choice depends on the fluid being measured and its temperature. Natural rubber and EPDM are commonly used for water applications. PTFE offers broader chemical compatibility and is used where the process fluid may attack elastomers. The O-ring material is specified in each product listing. Selection should be based on fluid compatibility and operating temperature to avoid swelling, hardening, or degradation of the seal.

Can MODMAG flowmeters be used for liquids other than water?

MODMAG inline magnetic flowmeters are designed for conductive liquids. While many models are listed for water applications, the electromagnetic measurement principle applies to any conductive liquid that does not coat or foul the electrodes. Liquids with low conductivity, such as hydrocarbons or deionized water, are not suitable without special electrodes. The wetted materials, including the liner and O-ring, must also be compatible with the process fluid. For non-water applications, review the O-ring material and body construction against the fluid's chemical and temperature properties.

What is the maximum voltage for MODMAG inline magnetic flowmeters?

The maximum voltage for the MODMAG inline magnetic flowmeters listed by 3G Electric is 240V AC. This applies to the power supply of the transmitter or converter. The meters provide either a 4-20 mA or frequency pulse output for signal transmission. Installation should follow applicable electrical codes and the manufacturer's wiring instructions. The voltage rating is stated in each product listing. For specific power supply requirements, refer to the product documentation for the exact SKU.
