Selection of the type of liquid level transmitter
Apr 17, 2017

1, Dan Falan liquid level transmitter

The Dan Falan liquid level transmitter has a flat flange and a cylinder flanged liquid level transmitter, which is used to measure the height of the liquid level by the gravity function of the measured medium. Dan Falan liquid level transmitter is suitable for high viscosity, easy crystallization of medium, generally used for open containers or equipment installation.

2, double flange liquid level transmitter

The double-flange liquid-level transmitter is a differential pressure transmitter, which provides a reliable measurement method for avoiding the contact of the transmitter with the isolating diaphragm. The main characteristics are the need to isolate high-temperature media and transmitters, measuring medium to the transmitter sensitive originals have corrosive action, suspended liquid or high viscosity medium, measured media due to environmental or process temperature changes and solidification or crystallization, replacing the measured media need to strictly purify the first-class measurement. Double flange liquid level transmitter is mainly used in the measurement of liquid level of sealed pressure vessel.

3, input-type liquid level transmitter

Input liquid level transmitter has rod type and range, the principle is based on the hydrostatic pressure measured by the liquid is proportional to the height of the principle, the use of diffusion silicon or ceramic sensitive elements of the piezoresistive effect, static pressure to turn into electrical signals. After temperature compensation and linear correction, the 4-20mADC standard current signal output is converted. Because this transmitter is easy to install, simple, adaptable and so on, from water, oil to the viscosity of a larger paste can be high-precision measurements, not by the measured media bubble, deposition, etc., generally used for open containers or equipment installation.
