Kaifeng electromagnetic flowmeter quotation

Overview

LDB200 series intelligentElectromagnetic FlowmeterEquipped with both Chinese and English display functions, low-frequency excitation and high-frequency excitation (for slurry measurement) are available for selection. It also has the advantages of high accuracy, low power consumption, and easy maintenance. This product is widely used in metallurgy, chemical industry, urban construction, environmental protection, food, medicine and other fields to measure the volume flow rate of conductive liquids such as raw water, sewage, slurry, acidic and alkaline solutions.

feature

Low frequency three value rectangular wave constant current excitation, not affected by power frequency and various stray interferences on site, works very stably and reliably.

The new technology of adopting non-uniform magnetic field and special magnetic circuit structure greatly reduces the volume and weight, and has the characteristics of small and lightweight.

Equipped with isolated RS485 communication function, isolated pulse output, microprocessor can automatically detect and reset air traffic control.

On site, parameters such as range, medium density, and flow unit can be modified online according to the actual needs of users.

There are no movable parts or obstruction components, and there is almost no additional pressure loss during measurement.

The measurement results are independent of physical parameters such as flow velocity distribution, liquid pressure, temperature, density, viscosity, etc.

Easy to use, simply connect the power supply after installation and it can be used. Instantaneous and cumulative quantities are directly displayed in Chinese on the upper and lower rows of the LCD screen.
