Divided Electromagnetic Flowmeter PCL-E20

Product overview

The PCL-E20 series electromagnetic flowmeter is a fully intelligent flowmeter developed using advanced technology both domestically and internationally. It has the characteristics of high measurement accuracy, high reliability, good stability, and long durability.

The PCL-E20 series strictly controls and pays attention to every step in the process of design, material selection, process manufacturing, production assembly, and factory testing; Equipped with calibration devices compatible with different calibers, each electromagnetic flowmeter manufactured has undergone real flow calibration. We have designed and developed specialized large-scale production software and hardware for electromagnetic flow meters, effectively ensuring the long-term high quality and high quality of our products. The product adopts a wide temperature range LCD display and a simple display interface, with complete and practical menu functions, simple and convenient button operation, and convenient on-site operation.


Features

 The measurement accuracy is not affected by factors such as fluid density, viscosity, temperature, pressure, etc

There are no intercepting or blocking components in the measurement pipeline, which will not cause pressure loss or blockage

Simple structure, convenient installation, and low requirements for straight pipe sections

 No mechanical transmission components, sturdy and vibration resistant

 Adopting a multi electrode structure, stable measurement, high accuracy, equipped with a grounding electrode, without the need for a grounding ring, saving costs

When power is off, EEPROM can save set parameters and accumulated flow values

The converter uses a low-power microcontroller for data processing, with reliable performance, high accuracy, and low power consumption. The LCD meter can display parameters such as cumulative flow rate, instantaneous flow rate, flow rate, and flow percentage

Bidirectional measurement system, capable of measuring forward and reverse flow rates

Low frequency rectangular wave excitation improves flow stability, reduces power loss, and has superior low flow rate characteristics

Application

Process control fields in industries such as water supply, heating, environmental protection, food, water conservancy, metallurgy, and pharmaceuticals.
