【Daily Question】12.1 What instruments are used to measure the liquid level in oil refining units? Answer three of them: glass plate level gauge, float level gauge, differential pressure level gauge
Glass plate level gauge, double flange level gauge, float level gauge, radar level gauge
Radar level gauge, ultrasonic level gauge, glass plate level gauge, float level gauge
Buoyant level gauges, differential pressure level gauges, float level gauges, flap level gauges, radar level gauges, acoustic wave level gauges – – – – – – – – – – – – – – – – – – – – – –
Float ball, double flange, radar, magnetic flap
1. Direct-reading level gauges, which utilize the principle of a communicating vessel, such as glass cups, glass tubes, and magnetic flip switches； 2. Buoyancy type: constant buoyancy type, variable buoyancy type ； 3. Differential pressure type ； 4. Others: Radar type is more common, radiation type (using a radiation source), capacitive type (we have used it before), ultrasonic type, photoelectric type, and radio frequency admittance type.
Using differential pressure level gauges, radar level gauges, and float level gauges
Double-flange differential pressure level gauge, float level gauge, ball level gauge, glass plate level gauge.....
Magnetostrictive level gauge, Radar level gauge, Pressure-type level gauge, Magnetic flap level gauge, Radio frequency admittance level gauge
Differential pressure level gauge, double flange level gauge, double flange level transmitter, float tank level gauge, float ball level gauge, glass plate level indicator, magnetic level indicator, radar level gauge, and so on
