8000XHT Operate at High and Low Temperature
Some of our customers require our products to be used under extreme conditions.
Proteus can supply a closed-cell foam insulator to prevent icing in cold conditions or protect workers from burns in higher temperatures.
Submerged flow meters cycling through 5 C to 80 C
The 8000XHT series flow meter provides an accurate, reliable, and cost-effective measurement of heat transfer fluids and other liquids. It is a revolutionary breakthrough in flow metering devices that deliver superior precision and reliability in flow and temperature measurement for critical heat-sensitive processes.
The 8000XHT has a unique operational mechanism that depends on embedded alternating magnets. The magnets (north and south) spin as the water flows through the sensor cavity, creating a spin in the rotor that transfer pulses through two flux concentrators to switch the two Hall-effect sensors mounted on the main electronics board. A microcomputer is embedded in the 8000XHT that monitor the rotational frequency of the rotor, scaling the factors into a flash memory to calculate the volumetric flow rate. The flow rate information is measured at an output between 0-10 or 0-5 VDC and 4-20 mA.
The 8000XHT has an adjustable relay trip point, programmed to change the state when measured outflow is below a preset alarm value. The tricolor LED on the device gives a visual indication of the liquid flow status. To ensure accuracy and to prevent unwanted tampering, each device comes with an alarm trip point, preset by the factory. The factory setting for upper flow limit is 15%; however, customers can request a customized trip point setting at the time of order.
Mil-Std 810 Ruggedized Applications
The 8000XHT Series – Custom designed to use in rugged applications as well as difficult EMI or RF environments (400A Magnetic Power Field or >188 GHz @ 10V/m) and with high-temperature fluids to +200C. The 8000XHT has been laboratory tested to Mil-Std 810 Method 514.5 – 514C-2 for 2 wheeled composite trailer with Shock to 20G.
The 8000XHT offers the capability to measure the liquid flow rate and temperature with a single instrument and only requires a single connection point in the entire pipeline. Customers also have an option device, i.e., Pt1000 Resistance Temperature Detector (RTD) probe that is mounted in the sensor body and provides a direct measurement of liquid temperatures between -80 to 200 degrees Celsius (-112 to 381 Fahrenheit).
