Differential Pressure Level Transmitter
The Deleetech DST8051 is an intrinsically safe explosion-proof differential pressure transmitter. By measuring the differential pressure between the liquid and gas phases in a container, it calculates the liquid level height and outputs a 4-20mA standard signal. It is suitable for liquid level measurement of low-temperature cryogenic liquids such as LH2 (liquid hydrogen), LN2 (liquid nitrogen), LO2 (liquid oxygen), LCO2 (liquid carbon dioxide), LN2O (liquid nitrous oxide), LAr (liquid argon), and LNG (liquefied natural gas). This product has strong anti-interference capability, high reliability, long service life, compact structure, strong environmental adaptability, and convenient installation.
Capacitive Level Transmitter
The DCT8051 capacitive level transmitter from Jiangsu Deleetech is a high-precision capacitive level transmitter designed specifically for special conditions such as LNG/liquid hydrogen vessels. It uses advanced capacitive measurement technology and is suitable for liquid level monitoring in low temperature, high pressure, and corrosive environments. It is compatible with various cryogenic media including LNG, LO2, LN2, LAr, LCO2, and LN2O, and is widely used in Dewar flasks, industrial gas cylinders, bioreactors, and other equipment. Standard features include two-wire 4~20mA output, wide-temperature LCD display, support for multiple unit switching, interference resistance with no false levels, stable measurement, intrinsic safety explosion-proof properties, and IP67 protection rating. It is widely applied in fields such as liquefied natural gas and liquid hydrogen storage tanks, serving as a safe and reliable level measurement instrument.
Capacitive Composite Level Meter
DCT8851 Smart Capacitive Composite Level Meter: a multifunctional industrial instrument integrating high-precision level, pressure and temperature measurement. It uses advanced capacitive sensing principles to achieve non-contact or contact continuous level monitoring by detecting changes in capacitance between the probe and the container wall. Built-in high-precision pressure and temperature sensors can be used in real time for density compensation and operational correction of the liquid level, significantly improving measurement accuracy, especially suitable for cryogenic liquid storage tanks such as LNG, liquid oxygen, liquid nitrogen, liquid argon and liquid hydrogen. It supports 4G wireless transmission and local LCD display, has an IP67 protection rating and a wide operating temperature range of -40℃ to 85℃, genuinely enabling maintenance-free, remote and intelligent liquid level management.
Differential Pressure Compound Transmitter
The DST8851 differential pressure composite transmitter from Jiangsu Deleetech is a composite remote transmitter capable of simultaneously monitoring liquid level, pressure, temperature, and acceleration. It is suitable for low-temperature storage tanks, tank cars, mini tanks and other scenarios. It supports dual 4G/LoRa signals and can interface with satellite communications and global roaming. Equipped with GPS/BeiDou dual-mode positioning, it offers timed, cached, and real-time data reporting modes. It supports OTA upgrades and cloud-based parameter configuration. Data can be viewed remotely via Web/APP and can also be integrated into the customer's own platform. The entire device is intrinsically safe and explosion-proof, ensuring stable operation.
Mass type level gauge
The MTUD is a smart mass-based level transmitter designed for cryogenic media such as LNG, liquid oxygen (LO₂), liquid nitrogen (LN₂), liquid argon (LAr), liquid helium (LHe), and other substances compatible with 304 stainless steel. It measures liquid level by detecting changes in the mass of the stored medium, offering high stability and strong anti-interference capability. The device features an RS485 (Modbus RTU) digital output, enabling seamless integration into SCADA or DCS systems for remote monitoring and data logging. With 24VDC power supply, IP67 protection, and wide operating temperature range (-40°C to +85°C), it ensures reliable long-term performance in harsh environments such as marine vessels, bunkering stations, and onshore storage tanks. Ideal for energy, chemical, and aerospace applications requiring high accuracy and robust communication.
Mass-type level meter 4-20mA
The MTM-A low-temperature medium level meter from Deleetech is specifically designed for measuring the liquid level in small-volume low-temperature bottles (tanks) and is suitable for measuring the liquid level of low-temperature cryogenic liquids such as LN2, LO2, LCO2, LN2O, LAr, and LNG. The product consists of a capacitive level sensor (probe) and a display converter (indicator), with the indicator featuring a display window, allowing calibration and parameter settings to be performed non-contact.
