Continuous Measurement Transformer Oil Pillow Level Monitoring Sensor

Module : DYP-U03

U03 oil level is a sensor device that uses ultrasonic detection technology to measure the height of oil and liquid substances without contact. Compared with traditional detection equipment, U03 oil level has high measurement accuracy and easy use. It can be installed externally (without destroying the container structure) and can be connected to networked equipment to realize network monitoring and management. The ultrasonic fuel quantity monitoring sensor is designed to optimize the mode of tank vehicle monitoring, and can also output more stable data for other liquids loaded on the vehicle.

Here comes the detailed specifications of DYP-U03 :

Items	Parameters	Unit	Remarks
Operating voltage	12~48	V	DC
Operating current	≤25	mA
Flat object measurement range	70~2000	mm
Measurement accuracy	≤5	mm
Resolution	≤1	mm
Reference angle	3~6°	°
Measurable container thickness	1~6	mm

Remarks:

(1) The higher the power supply, the lower the current.

(2) Normal temperature and humidity, 1 standard atmospheric pressure, the measured liquid is 0# diesel oil, and other liquids need to be explained when ordering.

(3) The target container has a wall thickness of 5mm, aluminum material, and 50~100cm diesel fuel, and changes the container inclination angle to test.

(4) The measurement distance is determined by the material and thickness of the container. For special materials or test thickness greater than 6.0mm, it needs to be stated when ordering.

Rated Environmental Condition

Items	Minimum	Typical value	Maximum	Unit
Storage temperature	-25	25	70	°C
Storage humidity		65%	90%	RH
Operating temperature	-15	25	60	°C
Operating humidity		65%	80%	RH

Note : (1) When the ambient temperature is 0-39°C, the maximum humidity is 90% (non-condensing);

(2) When the ambient temperature is 40-50°C, the highest humidity is the highest humidity in nature (non-condensing) at the current temperature.

Remarks : After the test, the module is determined to be OK after the function test, and the performance degradation rate is ≤10%

Product Features

DYP-U03ultrasonic sensor features non-contact measurement, eliminating the need to alter the container's shape or polish its surface paint. Housed in a metal shell with internal circuit potting and rain-proof design, it thrives in outdoor environments. External waterproof adhesive stickers enable simple installation and firm fixation. With wide voltage operation (DC 12~48V), it suits various vehicles, while the RS485 output interface ensures reliable data transmission. Leveraging high-frequency ultrasonic detection, it boasts strong solid penetration, fitting metal/plastic containers. Its high-stability measurement output integrates an anti-interference data processing model for intelligent environmental filtering/compensation, and the built-in high-precision calculation model delivers millimeter-level resolution for accurate measurements.

In industrial settings, the DYP-U03 shines as an oil tank level indicator, offering clear, real-time readings that help prevent overfilling or running out of oil. As an oil level sensor, it boasts a wide measurement range, catering to both small reservoirs and large industrial oil tanks.

This ultrasonic oil level sensor also features quick response times, ensuring that sudden changes in oil levels are detected immediately.

It integrates the high precision, high efficiency and wide applicability of ultrasonic sensors, making it an indispensable core device for various oil level monitoring applications.

Scope of Application

Module DYP-U03 mainly used in Monitoring of the fuel volume of tank vehicles, Liquid level measurement in storage tank, Container water level monitoring, Filling liquid gas measurement.

Mainly used in different oil tank level monitoring

Matters Needing Attention

1. The total length of the ultrasonic sensor transmission line is 8 meters by default, and the user cannot extend the wire length by himself.

2. When installing, ensure that the vehicle is parked on a flat road, and the height of the liquid level in the fuel tank is about 7cm.

3. When installing the ultrasonic sensor, you need to follow the installation instructions.

4. After refueling, the height change of the liquid level must be greater than 30mm, otherwise the oil level value will not be updated.

5. Test the alarm function, it will be effective after one minute after power on.

6. The higher the communication rate, the shorter the length of the signal line. When the communication rate is 9600bit/S, the length should be controlled within 8 meters, and when the communication rate is 128000bit/S, the length should be controlled within 3 meters as much as possible. Other rates depend on the communication conditions. Adjust between 3-8 meters.
