WK-100H Wall-mounted ultrasonic flow sensor high-temperature stability test analysis

How stable is the WK-100H wall-mounted ultrasonic flow sensor under high-temperature conditions? As a flagship product of Xi'an Shenghongchuang Instrument and Meter Co., Ltd., WK-100H, like the FV and JY-100 ultrasonic sensor series, performs excellently under extreme operating conditions and is an ideal choice for technical evaluation personnel.

1、Core challenges of ultrasonic sensors under high-temperature conditions

In industrial scenarios such as oil processing, metallurgy and other industries, ambient temperature often reaches above 80℃, and conventional flow sensors are prone to issues such as signal drift and component aging. WK-100H adopts special piezoelectric ceramic materials and military-grade integrated circuits, with its operating temperature range extended to -40℃~150℃, improving heat resistance by 20% over similar products such as the HF-3000 wall-mounted ultrasonic flow sensor. Test data show that after continuous operation for 500 hours at sustained 100℃, its flow measurement error is still controlled within ±0.5%FS, far better than IEC 60751 standard requirements.

2、Key performance test data comparison

By comparing competitive models such as TUC-2000E, the unique advantages of WK-100H are: 1）adopting a three-point temperature compensation algorithm to correct environmental temperature influence in real time; 2）the sensor probe shares military-grade sealing craftsmanship with the BY-CSB-1 series, with IP68 protection rating ensuring long-term stability.

3、Practical operating-condition validation cases

In a certain steel mill cooling-water circulation system, 12 units of WK-100F wall-mounted ultrasonic flow sensors have run continuously for 18 months. On-site monitoring data show: under periodic 90℃ high-temperature impact, the signal-processing system with the same source as WK-100H maintains measurement precision of ±0.8%, reducing maintenance frequency by up to 60% compared with the original JGTUF-2000S sensor. This case verifies Shenghongchuang Instrument and Meter's technical accumulation in the high-temperature fluid measurement field.

4、Technical evaluation checklist

For the core focus points of technical evaluation personnel, it is recommended to focus verification on: 1）step-response characteristics of the sensor during abrupt temperature changes; 2）zero-point stability after long-term high-temperature exposure; 3）compatibility performance with series products such as WK-100P. Test data show that in rapid temperature-change testing from 85℃→120℃, WK-100H needs only 43 seconds to return to standard accuracy, outperforming the B-level standard specified in ISO 4064:2017.

5、Industry solution value

As the technical upgrade model of the FV series, the WK-100H wall-mounted ultrasonic flow sensor is particularly suitable for: 1）steam flow monitoring in geothermal energy systems; 2）high-temperature medium metering in chemical reactors; 3）high-temperature cooling water circulation systems in power plants. Its modular design can be integrated with equipment such as TUC-2000E to form a distributed monitoring network, and through the HART protocol it can achieve system-level precision of ±0.2%.
