If I want to buy a pressure switch & 3-way valve for hot
water application then witch parameter I should consider.
IS there any effect of vortex in low pressure side of the transmiter after the orific in feed water line? if yes then what is the calculation?
how manys ways dp transmitter can be calibrated having range of -150 to 400mmwc,what side pressure u will apply?
What is actuator what is motorized control valve?
how control valve works?
WHAT IS A SYMPTOM OF FAULT WITH THE SPAN OF AN INSTRUMENT? 1)ZERO-POINT AND 100% ARE CORRECT BUT NOT A MID-RANGE. 2)ZERO-POINT IS CORRECT ,BUT 1005 INPUT IS NOT GIVING 100% OUTPUT. 3)LINEARITY PRBS. 4)1005 O/p IS CORRECT BUT ZEO POINT IS WRONG.
why use 50% lel methane gas concentration for gas detector calibration instead of 60% lel gas concentration whereas the hi alarm set at 60% lel.
please anyone suggest me some good intools training institutes with their place and contact nos.
