Ultem®PEI Plastic Machining
For machined parts requiring added strength, engineers turn to Ultem®. This high-performance thermoplastic is considered one of the best for exhibiting excellent strength and stiffness. Ultem® also maintains great dimensional stability at high temperatures (200°C).
Engineers turn to this material when they need parts machined for demanding applications in the Aerospace industry for aircraft and spacecraft and in Medical industry applications requiring repeated sterilization cycles.
As is the case with many high-performing plastics, understanding the machining characteristics of Ultem® is critical to producing a precision part. Many companies machine Ultem, but it`s critical to work with one that knows how to manage stresses in the material to achieve complex tight tolerance parts.

The drive coil and the feedback circuit vibrate at its resonant frequency, and the resonant frequency of the vibrating tube is related to the structure, material and quality of the vibrating tube. The quality of the vibrating tube consists of two parts: the mass of the vibrating tube itself and the mass of the medium in the vibrating tube. The quality of the vibrating tube itself is determined after each sensor is produced. The mass of the medium in the vibrating tube is the product of the medium density and the vibrating tube volume, and the volume of the vibrating tube is fixed for each type of sensor. The vibration frequency is directly related to the density. For sensors that determine structure and material, the density of the medium can be obtained by measuring the resonant frequency of the flow tube.
When using a wedge flowmeter , if a small amount of gas is stratified or wavy in the water pipe, the fault phenomenon shows an increase in error, that is, the flow measurement value does not match the actual value; if the flow is a bubble flow or a plug flow, the failure phenomenon If the measured value does not match the actual value, the output sloshing may occur due to the instantaneous covering of the electrode surface by the gas phase; if the gas phase of the cross-sectional area of ​​the horizontal pipe is increased in the stratified flow, that is, the liquid is not full, the output sloshing may also occur. If the liquid is not full, the liquid level is below the electrode, and the output is full.
Analysis of working principle of wedge flowmeter
When the fluid flows into the flow tube, it is forced to receive the vertical movement of the flow tube. During the half cycle of the upward vibration of the flow tube, the fluid resists the upward movement of the tube and applies a downward force to the flow tube; otherwise, the fluid pair of the wedge flow meter The flow tube exerts an upward force to counteract the downward movement of the tube to reduce its vertical momentum. This causes the flow tube to distort, and during the other half of the vibration, the flow tube vibrates downward, and the twist direction is reversed.
