Since the height of the filling is close to the tower top, the water eliminator does not occupy much space, and the overall height of the cross-flow tower is small, which makes it relatively compact compared with counter flow type, and therefore lower air inlet speed and power consumption as well.
The cross-flow tower adopts a water distribution system that will let the water drop fall naturally by gravity. Thereby, water distribution holes are not easy to be blocked, as water distribution is even and maximizes the performance of the tower fillings. The inspection manhole also enables routinely maintenance without machine shutdown.
A lower part of the cross-flow tower filling is submerged in the water, so that the water flows through the surface of the filling and directly falls into the below tank, making low noise.
The cross-flow tower fan is located in the middle of the Cooling Tower, while the filling, on both sides of the tower. So the amount of splashing water is very small.

And we know that the electronic amplifier circuit consists of a demodulator, an oscillator, an oscillation control amplifier, a current detector, a current control amplifier, a current limit controller, a reference voltage, a voltage regulator, and the like. Through their detection of the capacitive signal, which controls the oscillation frequency, and then convert it into a current output, such a process can drive its work.
In the long-term operation of differential pressure transmitters, there are a variety of faults. When dealing with faults, careful detailed observation and analysis should be performed to determine the general location of the fault and the solution steps, and then debugging and testing should be started. This can achieve a multiplier effect. In addition, the user is reminded to note that the meter must be calibrated and qualified after being repaired before it can be put into normal use. At this moment, we understand the pressure transmitter's working mechanism and troubleshooting.
The prone to malfunction when the transmitter is running
Pressure Transmitters The capacitive transmitter has a variable-capacity sensing assembly in the body, called a “δ†chamber. The sensor is a completely enclosed component. We know that the process pressure and differential pressure cause displacement through the isolating diaphragm and the filling liquid silicone oil to the sensing diaphragm. When the capacitance difference between the sensing diaphragm and the two capacitor plates is converted by the electronic components (4 to 20) Two-wire output of the mA signal. This is the mechanism.
