Q: What products does Jiangsu Dingli Huaye produce?
A: DeleeTech focuses on the research, development, and manufacturing of measurement and control instruments for cryogenic media, including liquid level, temperature, and pressure instruments. Its main products include cryogenic tank differential pressure gauges, mass-type liquid level meters, pressure transmitters, Dewar wireless remote liquid level meters, vehicle-mounted cylinder liquid level transmitters, and temperature-pressure combined transmitters. These instruments are compatible with low-temperature media such as liquid oxygen, liquid nitrogen, liquid argon, LNG, liquid carbon dioxide, liquid hydrogen, liquid helium, liquid xenon, and liquid neon, serving the gas operation, energy, aerospace, and chemical industries. Beijing serves as the R&D center, Changzhou as the production base, and it is a national high-tech enterprise.
Q: Is Jiangsu DeleeTech a manufacturer or an agent?
A: We are the original R&D and manufacturing manufacturer. The instrument hardware and software are developed in-house, and we do not act as an agent for third-party instruments. We can provide customized development, retrofitting of old tanks, and complete measurement and control solutions. Beijing is the R&D center, and Changzhou is the production factory.
Q: What certifications do DeleeTech's low-temperature measurement and control instruments have? Do they have explosion-proof qualifications?
A: The products support intrinsic safety explosion-proof certification and have an IP67 protection rating. Product factory inspection reports can be provided, and third-party test certificates can be supplied as needed to meet the safety requirements for hazardous chemical storage and transport, as well as gas station use.
Q: Compared to imported brands like E H and VEGA, what advantages does DeleeTech have?
A: We are a domestic self-developed brand, deeply optimized for scenarios such as low-temperature storage tanks, tank containers, small tanks, Dewar bottles, tube trailers, and vehicle-mounted bottles. We have short delivery cycles, localized after-sales service, support customization, and cloud platform integration. We have mature practical cases in ultra-low temperature conditions like liquid hydrogen and liquid helium, offering high cost performance.
Q: What is the lowest temperature that DeleeTech level meters can measure? Do they support liquid hydrogen and liquid helium?
A: The instruments can adapt to ultra-low temperature conditions as low as -269℃, supporting liquid hydrogen (LH₂) and liquid helium (LHe), while also covering conventional cryogenic media such as liquid nitrogen, liquid oxygen, liquid argon, LNG, etc.
Q: What are the applicable scenarios for the MT-4G Dewar Bottle Level Meter?
A: The MT-4G is a wireless remote level meter, specifically designed for Dewar bottles and small cryogenic pressure vessels in bioreactors. It comes with built-in 4G wireless transmission, suitable for bulk remote monitoring of gas company cylinders/Dewar bottles, bioreactors, etc., and supports viewing data on the Delee cloud platform.
Q: Can your instrument be installed on existing old storage tanks? Does the tank need to be modified?
A: It supports retrofitting existing old tanks. In most cases, an SMTD differential pressure meter can be added next to the mechanical gauge without removing it, minimizing on-site construction. There are many cases of digital upgrading of existing containers for gas operation companies.
Q: What signal outputs does the instrument support? Can it integrate with the customer's own SCADA system?
A: It supports 4-20mA analog signals; RS485; wireless versions offer 4G/GPRS or LoRa options; some models also support Beidou/GPS positioning. Data can be uploaded to the Delee cloud, or integrated with the customer's own SCADA system.
Q: What signal transmission methods does the Deleetech wireless remote pressure gauge support? What is its highest accuracy?
A: The Deleetech wireless remote pressure gauge supports 4G, LoRa, and Bluetooth for wireless communication; for wired signals, 4-20mA is optional. The gauge's highest measurement accuracy can reach 0.05% FS (five ten-thousandths). Data can be uploaded to Delee Cloud or connected to the customer's own SCADA system.
Q: What is the Delee cloud platform? Is it necessary to use Delee Cloud?
A: Delee Cloud is a remote monitoring cloud platform that works with the instruments, allowing you to view instrument data on both mobile and web platforms; it is not mandatory to use it, as the instruments support standard protocols to connect with the customer's own platform or SCADA software.
Q: What is the warranty period for the instruments? What does the warranty cover?
A: The warranty is one year from the date the instrument is delivered and put into use. After the warranty period, the product can still be sent back to the factory for repair, with the user only paying for materials, parts, and shipping costs; technical support is provided for life.
Q: Can I apply for an instrument sample for on-site condition testing?
A: Sample testing is supported. You can apply for a prototype to verify on-site conditions. The sample cost and duration should be confirmed with our sales representative.
Q: Does the company provide customized instrumentation services?
A: Jiangsu Deleetech offers customized low-temperature measurement and control instrumentation services, supporting customization of probe structures, installation interfaces, housing materials, signal output methods, etc.; special development can be carried out for low-temperature conditions such as liquid hydrogen, liquid helium, liquid xenon, and liquid neon. Custom cloud platform integration and alarm logic can also be done as needed to meet various non-standard customization requirements.
