First of all you have to know the gravities of the liquids you want to measure.
For example crude oil's gravity is 0.87 and water's gravity is 1.
A level transmitter uses 2 inlets, including the area of the level you want to observe.
You meter the distance (the height) between the two inlets.
CALIBRATION:
You fill the container with the heavier liquid, till the gravity's percent (%). Adjust for ZERO.
Fill till 100% to have the SPAN.
The gravity selector must be at the right position.

Why power amplifier used in FM transmitter?
Amplifier is used in an FM transmitter to increase the level of a signal suitable for transmission
How level transmitter works?
It just transmits the level of the fluid into electric signal to level indicator and this level indicator will show current level of fluid.The whole setup is used for level measurement. A Level Transmitter is simply an instrument that provides continuous level measurement. Level transmitters can be used to determine the level of a given liquid or bulk-solid at any given time. This is different to a level switch which only alarms when the level of material (liquid or bulk-solid) reaches a predetermined level.
What is a DIY method to calibrate a tripod mounted transit level or check it for accuracy?
To check for accuracy, set up water level, then shoot the ends.

What is Low Level AM Transmitter?
There are two types of AM transmitters, High-level and low-level. Low-level transmitters don't have to go through quite as many amplifiers as high-level AM transmitters, as well as consuming less power than the high-level counterparts, but aren't as efficient.
How do you calibrate displacer type level transmitter?
You have to specify which type of calibration you want to perform on the transmitter dry, wet or online calibration ?
How do you calibrate level switch?
how we calibrate the level switch
How do you calibrate differential pressure transmitter in field?
well you just need to slide it inside it yiou also need a life
How do you calibrate smart transmitter for flow measurement?
use the communicator and apply 4 MA which is your zero them apply 20 MA which is your span. .
How do you calibrate an altimeter?
Calibrate it at sea level and then again at an elevated position where the height it known. This would allow one enough reference point to calibrate it accurately.
What is a Rosemount 'smart' transmitter?
how to interface with rosemount temperature tarnsmitter thro laptop -is there ant software
The interface on the access point used to connect to the existing wired network is typically called what?
transmitter
How do you calibrate a digital oral thermometer?
One should have a standard certified temperature calibrator system before attempting to calibrate a temp. transmitter. I believe you want to calibrate the temperature sensor connected to a transmitter and to an indicator. There are three things in all. Temp. sensor it could be RTD or TC. Temp transmitter which transmits the sensor input to the indicator on which one can read the temperature. All three can be calibrated separately or together. If together it can be called loop check. Now to calibrate the transmitter know the range the transmitter and the output signal it is designed for. Say it is designed for 4-20 mAmp signal output and the range is 50'C to 200'C. It means the transmitter is supposed to give 4 ma output when it is measuring 50 'C and 20 ma when it is measuring 200 'C and be liner through out the range. Connect the transmitter to standard 4-20 ma meter. connect the standard resistance equivalent of 50'C in steps of 50'C. Measure the map signal with each step of 50'C equivalent of resistance connected. with increase in step the mamp must increase correspondingly linearly upto 200'C on the meter. Repeat the same in decreasing order in steps from 200'c to 50'C and measure the mamp. Adjust the potentiometer if any on the transmitter in case of deviation. Let the transmitter be with in its defined permissible error range while adjusting the transmitter

How do you select the range for the DP level transmitter?
BY Product Specification
When you will do suppression in level transmitter?
If you are mounting the transmitter below the datum line of the tank, the transmitter signal will go above 4 mA when the High side impulse line fills up and this will give a zero error compared to the tank actual zero level.
What are the field instruments used in power plants?
Temperature: Thermocouple, RTD, Temperture Transmitter. Flow Transmitter, DP ransmitter, Pressure Transmitter, Pressure switch, Radar level Transmitter, PLC system, Woodward Governor, Ultrasonic flow transmitter. Relay, Control Valve, ON/OFF valve.
