i have one tank of 500mm height, which is in under vacuum of 735 mmHg, I want measure level of the same using DPT , SO WHAT WILL BE THE URV & LRV, DENSITY OF THE TANK FLUID IS 0.95. is there necessary to fill the LP side with fluid.
7 17070Working principle of vibration sensor?, Type of vibration sensor? , Can we use vertical instead of horizental or vice versa?, if not Reasons?
2 11670can any one pl explain me in brief that how we select the leakage classification in valve,means for liquid or gas there is any standard for selecting leakage classification or its depend upon valve size or any any other parameter.
3 5871Foe selecting control valve if i have the min,normal & max data of flow rate,inlet pressure& outlet pressure,inlet tem.&density than how can i assure that these data are correct,pl. let me know if therew there is any method to check it.& also how we assure that the Cv we get from this data is suitable for valve for controlling require flow.
