ALTImass Type U High-Accuracy Flowmeter
Request a Quote
The OVAL ALTImass Type U is a high-performance Coriolis flowmeter with a U-shaped flow tube optimized for stability and accuracy.
Equipped with an advanced transmitter featuring a large touch-panel display, self-diagnostics, error logging, and parameter backup, it ensures reliable operation in demanding environments.
Ideal for routine flowrate monitoring as well as extremely low flow and short-duration filling processes, it offers enhanced zero-point adjustment, vibration detection, and superior zero stability. Supporting both high and low temperature service models, the ALTImass Type U is designed for versatility across liquid, gas, and steam applications.
Features
Enhanced maintenance functions
● Zero-point adjustment function (2 methods: Status input by front key operations or adjustment button on the transmitter)
● Error logging function
● Clock function (Accmlated time from power on is saved in the transmitter)
● Factory default parameter reloading function
● Parameter backup function to the display unit
Satisfactory self-diagnostic feature
● Status of the flowmeter is presented by two-color backlights (white, orange) and two LEDs (red, green).
● Input signal (sensor) check for disconnection
● Pipeline vibration check
Large-size display! Settings can be changed in the field.
Display screen is large and easy to view with a backlight facilitating setting in a dark place.
Improved zero stability
