How to do on-site Setting for Ultrasonic Level Sensor

It?is?normal?to?find?that?the?ultraonic?sensor?will?has?some?value?error?and?when?this?appreas,?we?should?adjust?and?debug?it?with?re-setting;?This?article?introduce?how?to?set?the?ultrasonic?level?meter?on-site

1.?Displayer?value?is?not?the?real?distance?from?sensor?to?liquid?level:

It?indicates?that?the?sensor?do?not?measure?the?liquid?level?correctly?and?get?another?distance?value?from?other?ojectives?such?as?bulge,?step,?cross?beam,?the?nozzle?or?blind?area?of?the?extension?pipe?become?larger?and?so?on;?please?find?this?objective?in?the?distance?which?is?bing?shown?in?displayer;?if?the?Max?liquid?level?is?under?this?objectives,?then?can?set?the?blinding?area?to?avoid?this?problems;?if?the?liquid?will?cover?this?objective,?then?can?change?the?sensor?position,?tilt?the?sensor?slighly,?add?the?static?tube?etc...

2.?Liquid?Level?value?jumps

If?the?data?jump?is?less?than?125?px,?the?response?speed?can?be?reasonably?selected?through?the?menu?P05.?If?the?data?jump?is?greater?than?125?px,?it?shows?that?there?are?large?ripples?in?power?supply?and?ground?gas.?Solutions:?equip?instrument?with?DC24V?power?supply?alone;?add?4?~?20mA?isolator;?sensor?has ?good?connect?on?the ?ground?and?other?methods.

3.?There?is?no?value?dispaying?on?the?screen:

Please?check?the?supply?voltage?and?switching-on?current?of?the?instrument?first.?The?supply?voltage?must?be?greater?than?18V.?The?switching?current?of?the?instrument?is?about?3.5mA.?Start-up?current?is?greater?than?4mA?or?less?than?2.5mA.?Instruments?must?be?repaired?at?the?factory.

4.?Can?not?get?liquid?level?value:

Please?check?whether?the?measurement?range?exceeds?the?Ultrasonic?Level?stroke?range?---(increase?the?meter?range?back?to?the?factory),

Whether?the?probe?is?vertical?or?not;

Whether?there?are?bubbles?or?floating?objects?in?the?liquid?level?(using?static?wells?or?adding?wave?tubes,?see?3.4);

When?the?liquid?level?is?high?or?close,?the?sensor?can?display?data,?while?the?low?liquid?level?or?long?distance?away,?the?meter?shows?---(probe?power?is?not?Enough,?return?to?the?us?to?replace?the?probe
