Ultrasonic works on Doppler and time transits. time taken for travel transmitter to receiver
Radar works on Echo generate by waves I mean reflective time and pressure of echo on quartz

Yokogawa CENTUMVP R6.09 unable to download to Engineering Station with ExaOPC R3.75 The issue is when I try to download the common project section to the Engineering Station (STN) from the HIS in System View, it is unable to connect. The error displayed is: WARNING: Could not connect to equalize destination. (7001) Retrying. Number of retries = 0/1 ERROR: LdXopsLoadMain: connect error 10060 ERROR: Processing terminated due to connection error. (7002) Equalization end with errors.

Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =
