Product Description

 For F550 long range ultrasonic level sensor, the measure range has 2m/5m/12m/30m measure range for select. And this sensor integrate wifi/zigbee/gprs/gps&gprs module into the device to realize remote monitor fuel level.For more detailed information, please leave message to me. Best regards.

Overview

The F550 is one type of ultrasonic level sensor which measure the air height in the container directly and calculate the level height based on the total height of the container. The resolution is 1mm or 0.1%FS (the bigger value).

It is applicable for the close container or open container.  Furthermore it can calculate the volume of the container or the liquid. As with RS485, it is easy to integrate into the embedded system or SCADA.

In order to realize remote monitoring, there are wireless version for F550, including zigbee, Wifi, GPRS, 3G. Furthermore, GPS module is one optional for the F550. As a result, F550 can be used as gps tracker also.

Installation

Installation & Calibration

After installation, the user should input the total height, tank type and other parameter in order that the sensor can calculate the liquid height, volume and etc.

Installation

The ultrasonic transducer should be vertical (90 degree) to the liquid level.   

The installation should not be near to the side to avoid the ultrasonic beam contact with the side and echo back.

The ultrasonic transducer should be try to higher +20cm than the maximum liquid level. (the 0-20cm is the blind area for the transducer).

Calibration

For 0-5V version, the user should measure the total height from the transducer to the minimum level. And use this value to minus the air height value (calculate by the 0-5V output according to the measurement range), then the liquid level is figured out.

For RS232/485 version, the user can directly configure the maximum height into the sensor, and the sensor will output the liquid level based on this input value and the air height.  Of course, if not input maximum height, the air height is still output. 

If user want to get the liter in the tank, user should create the table between height and liter through adding fuel and measuring.

FAQ

Q1 Can we use the DF550 to detect solid level/height?

Yes, the DF550 is air distance sensor, solid level sensor and liquid level sensor. It can directly measure the distance from transducer to the solid/liquid. Then it can draw out the solid height or liquid height. Formula is solid height = total height- air height.

Q2 Can the DF550 use for chemical tank?

Yes, the DF550 can use for chemical tank. And it has PTFE/PVD version which is good for erosive environment.

Q3 Can the DF550 be used for open cover case?

Yes, it can use for covered or open case. E.g. It can be used to detect tide / river level or solid height.

Q4 What is the IP level for the DF550?

It is IP66.

Q5 Can the DF550 be used for high temperature case?

No, if more than 70, the DF550 maybe work out of control.

Q6 Is the DF550 with ATEX certificate?

No, it is qualified with CE EMC, RTTE, Rohs. But not with ATEX certificate.

Q7 Can the DF550 used to measure powder height?

Yes, If the powder is stable on the ground, not floating in air. It can measure.

Q8 Is the DF550 effected by the smoke?

Yes, if there is smoke in the way from transducer to the measured solid/liquid, the measured data will be effected or out of work.

Q9 If the DF550 is not vertical to the solid level, can it work?

No, if it is far from vertical, it can not work. If it is near to vertical (difference<8°), it can work.

Q10 Can we connect the DF550 with dry contact (relay)?

Yes, the DF550 has version of 0-5V output. If the dry contact can be triggered by the volt in this range (0-5V), it can work.

Q11 Can the DF550 use to measure wine tank?

Yes, it can do.

Q12 Can the DF550 use to measure underground tank?

Yes, it can do. It can be install at the top of the tank, or lifted much more than the tank.

Q13 Can the DF550 work with bluetooth?

No, the DF550 has version with zigbee, wifi, gprs, wcdma as well as 0-5V/RS232/RS485. But it does not have version with bluetooth now.

Q14 Can we use the DF550 to measure 10 meters tank?

Yes, the DF550 has version 2meters, 5 meters, 12 meters, 30 meters. The user can select the proper version based on their application.

Q15 Can we use the DF550 for covered container?

Yes, it can work. But the user should drill hole at top. Below is the recommend installation for underground tank.
