 Introduction

 Based on the advanced Coriolis effect and technology, Coriolis meters directly measure mass flow, density, and temperature with precision up to ± 0.1%, ±0.15%, ±0.2%. Coriolis mass flow meters provide highly accurate flow measurement for liquids and gases across industries like oil, gas, chemicals, and food production.

Coriolis flow measurement solutions offer you three choices: U-type Coriolis mass flow meter, triangular Coriolis mass flow meter, and straight tube Coriolis mass flow meter. All of them are seamlessly tailored to meet every specific demand of your industry.

 Characteristics

  • High-Precision Measurement: Accuracy can reach up to ±0.1% or even higher, delivering highly precise mass flow measurement. This is achieved through direct measurement of mass flow based on the Coriolis principle, which is minimally affected by changes in fluid temperature, pressure, viscosity, and density. 

  • Multi-Parameter Measurement Capability: In addition to mass flow, it can simultaneously measure parameters such as fluid density and temperature. By integrating these measurements, it provides a comprehensive understanding of the fluid’s properties and state.

  • Wide Turndown Ratio: The turndown ratio typically reaches 100:1 or higher, enabling adaptation to a broad measurement range—from very low to relatively high flow rates—making it suitable for various industrial processes with different flow scales.

  • Excellent Repeatability and Stability: With proper maintenance, the device maintains consistent performance over long-term operation. Its output signal exhibits high repeatability, supporting precise process control and quality monitoring.

  • Configurable output: BPM Transmitter can provide 4-20mA current output to the outside through active or passive means, which is used to represent mass flow, volume flow, density and temperature. It can also provide 0-10kHz pulse output to the outside through active or passive means, which is used to represent mass flow and volume flow.

  • Standard RS485 interface mode: BPM Transmitter uses RS485 interface based on MODBUS RTU communication protocol. Through digital communication, all measured values and intermediate values can be output, and the host computer communication software provided by our company can be used to view, store, and modify data variables.

  • Temperature and pressure compensation: all internal circuits of the Transmitter adopt industrial-grade low-temperature drift series components, so that the Transmitter is less affected by the ambient temperature, ensuring the measurement accuracy within the normal operating temperature range. 

  • Convenient man-machine interface: the Transmitter is equipped with lightsensitive explosion-proof buttons and OLED display. The query and display of mass flow, volume flow,density,temperature and the calibration of the calibration of zero point can be completed at site through buttons(the above operation does not require to screw the front cover).
