Key Features

Utilizes a 32-bit ARM CPU for high reliability and fast operation speed.

Intelligent control algorithms and smart functionalities greatly simplify parameter settings, making instrument operation extremely straightforward.

Standard Modbus communication interface for easy connection with other systems.

Multiple-key operation, convenient and quick.

Specially designed power circuitry boasts high reliability and a wider voltage adaptability range. It overcomes the drawback of conventional switch-mode power supplies, which are only suitable for low-voltage operation and not for high-voltage power supplies exceeding 260V.

Dual data storage circuit, all parameters are backed up, and can be automatically restored if data is interfered with. Additionally, the instrument is equipped with features to restore factory settings and restore backups.

Utilizing a superior ADC circuit, it boasts not only faster speed and higher accuracy but also avoids the drawback of common programmable ADC circuits that fail to operate normally due to lost configuration files caused by interference.

Pulse shaping circuits are added to the input side to enhance the accuracy and stability of speed measurement results.

The gauge features multiple function modes, including constant speed, dual-speed, fixed speed, metering, winch, and impulse flowmeter modes. Additionally, it can utilize analog output for advanced control, enabling speed regulation without a speed-measuring device.

Flexible control methods. The gauge can be set for flow and start-up operations via keyboard, communication, or interface. Additionally, the measurement method can be selected for speed start.

In the flowmetering method of flush plate flowmeters, the instrument features 4-point linearization processing with a volumetric operating mode. In the event of a failure in the velocity sensor or load sensor, the instrument can refer to the normal operating data for open-loop control. Manual operation function. This feature facilitates system testing.

The instrument features parameter setting, interface testing, calibration functions (zero-point, chain code, and physical calibration), parameter backup and restore capabilities, and supports direct keyboard modification of zero points and coefficients.

Version 2.0 adds bilingual display, which can be selected to show either Chinese or English based on parameters.
