Overview

The Grylls5950 series mass flow controller uses the principle of capillary heat transfer before and after temperature difference calorimetry to measure the mass flow rate of gas, which is not affected by temperature and pressure. Amplify the flow signal measured by the sensor, compare it with the set voltage, and use the difference to drive and control the regulating valve, closed-loop control the flow rate through the channel to be equal to the set flow rate.

Product Details

The Grylls5950 series quality flow controller supports digital input/output, and the device itself can be equipped with a multifunctional touch display screen. It can also use a flow computer to control and display flow, and can provide optional multimedia/multi range functions. The Grylls5950 series mass flow controller adopts a thermal principle, with short preheating time and an accuracy of up to 0.5% F.S. It has zero drift, tubular diversion, and is not easily blocked. It is suitable for various low-pressure and high-pressure pipelines, with a flow rate of up to 6000SLM and can achieve digital/analog control modes; The product adopts high-speed control algorithm to make the response time of the entire flowmeter more outstanding. The product supports RS-232 Serial / RS-485 Serial / Modbus RTU / PROFIBUS / EtherNet/IP/ DeviceNet / Modbus TCP/IP / EtherCAT / PROFIBUS-DP communication protocol The Grylls5950 series consists of components such as mass flow sensors, laminar stratification components, flow controller regulating valves, and amplification control circuits. It is made by utilizing the heat transfer effect of flowing fluid to change the thermal conduction distribution of measuring capillary wall temperature distribution.
