Jiangsu Deleetech has been deeply engaged in the field of low-temperature medium measurement and control for many years. Its core team has over 30 years of experience in sensor and industrial instrument R&D, focusing on three core measurement dimensions: liquid level, pressure, and temperature. The company provides a full-chain digital solution from sensing instruments, IoT communication at the transmission layer, to cloud systems at the platform layer. As an original manufacturer integrating R&D, design, production, installation and modification, and after-sales maintenance, it ensures no service gaps from intermediaries. Leveraging its mature on-site construction and full-cycle after-sales system, it offers one-stop SMTD wireless remote differential pressure meter services for new low-temperature tank installation and mechanical liquid level gauge tank modification for gas enterprises, which is a key reason why many oxygen, nitrogen, and argon tank operators prefer us.
一：Four Major Industry Pain Points of Traditional Level Gauges ：
Pain Point 1: Poor measurement accuracy, untraceable inventory losses Traditional mechanical level gauges have only a Class 2.5 accuracy. Long-term use can easily lead to data drift and reading distortion, directly causing confusion in tank inventory records. Monthly stocktaking and supply-demand reconciliation often result in tonnage discrepancies. Hidden losses occur frequently and the exact causes cannot be pinpointed, leading to continuous economic losses for enterprises. SMTD Solution: ±1% high-precision measurement, simultaneous monitoring of level and pressure, full data retention with traceability, accurate statistics of media inflow, outflow, and storage data, achieving refined inventory management and completely solving the problems of reconciliation confusion and unexplained losses.
Pain Point 2: Inefficient manual meter reading with safety and management risks: The traditional approach relies on manual climbing to read meters, making work difficult in extreme cold or heat, with low efficiency and high human error, and posing safety risks when working at heights. Additionally, static data is severely delayed, preventing management from grasping the status of storage tanks in real time and making it difficult to promptly avoid production hazards caused by pressure or liquid level anomalies. SMTD Solution: Equipped with a built-in Industrial 4G wireless module, it automatically uploads data to the cloud without the need for wiring (4G/485/4-20mA transmission options available). Data from storage tanks can be viewed in real time on mobile phones or computers 24/7, with automatic alerts for anomalies, enabling unattended intelligent monitoring, reducing costs and improving efficiency while entirely avoiding the risks of manual operations.
Pain Point Three: Poor equipment compatibility and lack of after-sales maintenance assurance: Most instruments are only compatible with general operating conditions, and after purchase, issues such as incompatible interfaces, poor low-temperature adaptation, and difficult commissioning often arise. Additionally, manufacturers do not provide on-site technical support, leaving abnormal data and equipment failures unattended. Third-party teams are unfamiliar with cryogenic processes, leading to equipment idleness and malfunction.
Deleetech offers an end-to-end dedicated service to fundamentally solve implementation and maintenance challenges: 1. Customised operational survey: Business engineers provide one-to-one consultation on site conditions and tank parameters to create tailored installation solutions, preventing compatibility issues from the outset. 2. Non-destructive and safe transformation: Dual mode of remote guidance and on-site commissioning, preserving the original tank structure, parallel calibration of new and old equipment, ensuring compliant and safe modifications. 3. Practical on-site training: Free operational training for staff, teaching data monitoring, alarm handling, and basic troubleshooting to enable autonomous maintenance. 4. Full-cycle after-sales support: 7×12-hour technical support, remote diagnostics, OTA upgrades, one-year full equipment warranty, and lifetime technical consultation and spare parts service. 5. System compatibility integration: Can be deployed locally, integrated with the company's own management systems, allowing centralised data aggregation and unified control across multiple tanks, meeting scalable operational requirements.
