Measurement of flow rate for ultra-low temperature liquid nitrogen and liquid oxygen

Liquid nitrogen, also known as nitrogen gas in liquid form, needs to be below zero150The liquid of the product needs to be measured for this medium, and an ultra-low temperature mass flowmeter can be used for measurement. Guangzhou Dichuan Instrument Co., Ltd

Adopting efficient insulation technology to effectively controlLNGWhen the low-temperature medium flows through the sensor and exchanges heat with the outside, it reducesLNGWait for the low-temperature medium to vaporize in the pipeline, thereby reducing the impact of gasification on flow measurement. The accompanying transmitter adopts a digital signal processor（DSP）Processing the collected signals, with the ability to determine the real-time status of the medium and other intelligent self diagnostic functions.

Product Features:

Adopting a multivariate digital processing system. Enhanced signal filtering, greatly improved sensitivity and accuracy of signal measurement, accelerated system response time, and made measurement more reliable;

The adoption of multivariate digital processing systems makes the system composition more flexible and convenient. In many cases, multivariate digital processing system modules and sensors can form a complete flow measurement system without the need to configure a flow converter. for exampleCNGTheLNGGas dispenser system, quantitative control system, flow or density single parameter measurement system, etc;

High measurement accuracy, the precision of mass flow measurement can reach0.1%-0.2%The density measurement resolution can reach0.002-0.02g/cm^3The temperature measurement error is less than0.5Degree;

● Implementation of density and temperature measurement functions, which can derive medium concentration measurement functions (for two-component media);
