CDS1000 – Cryogenic Flow Totalizer

  • Programmable 2-10 point flow meter linearization
  • Pump control based on product or pump housing temperature to protect pump seals
  • Optional pump protection based on monitoring pump discharge or differential pressure

The CDS1000 Cryogenic Flow Totalizer is a microcontroller based rate/totalizer that offers industry leading features that protect delivery system assets.


The CDS1000 Cryogenic Flow Totalizer is an effortless, field programmable complete delivery system that accurately computes and displays in real time flow parameters in digital and graphic format.

The features-rich CDS1000 includes temperature compensation for 10 products, pump temperature and pressure monitoring, a detail screen displaying current operating conditions and maintenance reminders. Additionally, both RS232 and Bluetooth forms of communication are standard.

The system operates seamlessly with our TMC Cryogenic flow meters to deliver proven results for low-temperature requirements. The CDS1000 monitor is front keypad programmable and allows for custom ticket setup, and linearization for enhanced metering accuracy.

The CDS1000 monitor can also be equipped with our handheld, wireless MZ320 Bluetooth Printer for effortless ticket printing.
