The tank truck cannot be filled with oil because the anti-overflow probe or anti-overflow socket is damaged. If we have an anti-overflow detector, we can first use the anti-overflow detector to check and directly rectify the problem. If there is no equipment and we don’t know where the problem is, we can contact the tank truck manufacturer for after-sales processing.
The anti-overflow detector is used to detect the wiring and accessories of the anti-overflow and anti-static system of the bottom-filling tank truck to ensure the normal use of the tank truck. The oil single-head type and double-head type are configured to meet the various needs of customers.
In order to prevent the tank from overpressure and overflow accidents during bottom filling, the bottom-filling tank truck needs to be equipped with an anti-overflow probe. When overfilling, the anti-overflow probe sends an alarm signal to control the oil spill electrostatic protector of the oil launch station to stop filling and ensure safe production.
The UZK-DL piezoelectric anti-overflow probe adopts the “piezoelectric” working principle, which is similar to the tuning fork principle. It generates vibrations by crystal excitation. The vibration frequency of the sensor in the air and liquid is different, and the switch signal is output by detecting the change of frequency. Frequency change is a physical property of the sensor. It is not limited by light, and is not affected by environmental changes such as turbulence, bubbles, stirring, etc. It is impact-resistant and stable and reliable compared to other liquid level sensors. It has stronger anti-interference ability.
Performance characteristics:

Products commonly used with anti-overflow probes:
The anti-overflow anti-static sensor used for bottom loading consists of three parts: anti-overflow probe, socket, and grounding sensor. It is usually equipped with a probe detector to detect whether the equipment is normal at any time.
Multifunctional compartment socket S02
Compartment display, sound and light alarm, with self-test function, can detect the probe rod and grounding status.
Probe tester CTB-IV-01
Suitable for automobile modification factories or tank trucks to carry with them. It can detect whether the anti-overflow probe rod and socket on the tank truck are normal at any time to avoid the problem that the tank truck cannot deliver oil due to equipment failure when it arrives at the oil delivery platform.
The anti-overflow probe rod is suitable for liquid tank trucks. It detects the situation in the tank during bottom-loading oil loading. It is used in conjunction with the control system of the liquid loading platform to ensure the safety and reliability of bottom loading and prevent overflow or dangerous situations. It is used with the anti-overflow socket to transmit electrostatic signals and overflow signals between the tank and the platform to ensure safety and stability when performing bottom-loading.
The grounding bolt is fixed on the chassis of the car to detect the grounding status of the liquid tank. It is made of pure copper to avoid corrosion and conductivity. The three constitute an anti-overflow system.
(I) Anti-overflow probe rod
The anti-overflow probe rod is installed on the manhole cover of the tank truck, or independently installed on the top of the tank. It detects the refueling situation when filling oil products from the bottom. It is used in conjunction with the control system on the oil loading platform to ensure the safety and reliability of the bottom loading and avoid oil overflow. The rod length and material can be customized according to customer needs.

(II) Tank truck self-detection anti-overflow socket
Features of self-detection anti-overflow socket:
- Optical sensor, using optical principles to detect the liquid level in the tank truck cabin, and provide liquid level status signals to the oil depot oil distribution control system. The product is safe, stable and has a fast response speed.
- It complies with API standards, is compatible with API optical plugs, and is converted to bottom filling system design to provide standard API signals.
- It can detect 6 overflow prevention probes at the same time and supports API standard overflow prevention system docking.
- It has sound and light alarm function and can detect the connection status of grounding bolts.
