Test Method for Thermostat Performance for On-line Densitometer Verification
The verification regulation for online vibrating tube liquid density meters states that the stability of the liq-uid temperature inside the on-line densitometer during the verification process needs to reach±0.05℃.This general choice is to install the on-line densitometer in the thermotank,which provides an experimental environment with cer-tain temperature control accuracy and uniformity at specific temperature points for the on-line densitometer.In order to meet the temperature stability requirements of the online vibration tube liquid density meter verification regulation,the performance of the thermotank must reach a minimum temperature deviation,temperature uniformity within 2℃,and temperature fluctuation within 0.5℃.This article conducts experiments based on the"Environmental testing equip-ment inspection method part 2:temperature testing equipment",and also simulates the temperature field of the ther-motank based on Fluent,verifying that the temperature deviation,temperature uniformity,and temperature fluctuation of the thermotank meet the indicator requirements.
