Typical use of Wall-Mounted Ultrasonic Flowmeter

Wall-Mounted Ultrasonic Flowmeter Application Cases

Wall-mounted ultrasonic flowmeters feature core advantages such as clamp-on/insertion installation, non-contact operation, no pressure loss, and easy integration into automatic control systems, making them widely used in municipal engineering, industrial production, environmental protection, energy, and other fields. Below are 5 directly applicable typical cases, including solution key points and application effects.

1. Municipal Water Supply: Long-Term Measurement of Aging Large-Diameter Pipes (KROHNE OPTISONIC 6300 W)

- Scenario: A 70-year-old carbon steel raw water pipeline with DN2300, where shutdown and pipe cutting are not feasible.

- Solution: Wall-mounted UFC 300 W converter paired with clamp-on sensors installed in Z-mode, equipped with IP68 stainless steel guide rails, and 4-20mA signal transmission to the central control system.

- Effect: Non-stop production installation, long-term stable accuracy, resistance to flood and pipeline aging impacts, and low maintenance requirements.

2. Sewage Treatment: Discharge Monitoring of Sludge-Containing Sewage (Chongqing Tangjiatuo Wastewater Treatment Plant YST305-D)

- Scenario: Flow measurement of sludge mixture discharge, requiring continuous monitoring and corrosion resistance.

- Solution: Doppler wall-mounted host with clamp-on sensors, RS485 connection to the environmental monitoring platform, and automatic cumulative discharge calculation.

- Effect: Over 99% recognition rate for sludge-containing sewage, IP68 protection grade, no contact pollution, and compliance with environmental data upload regulations.

3. Heating Supply: Secondary Network Heat Measurement (Shandong Heating TUF-2000F)

- Scenario: Hot water flow and heat allocation in residential area secondary heating networks, with wide flow range under low-temperature conditions.

- Solution: Wall-mounted host integrated with PT100 temperature sensors, clamp-on installation, and connection to the heating monitoring system.

- Effect: 150:1 turndown ratio, ±0.5% low-temperature measurement accuracy, support for heat settlement, and facilitation of hydraulic balance adjustment.

4. Chemical/Petrochemical Industry: Circulating Water and Raw Material Monitoring (A Petrochemical Plant SWU801)

- Scenario: Harsh environment with 1000ppm H₂S, for circulating water and chemical raw material pipelines.

- Solution: High-temperature resistant wall-mounted host with insertion sensors (for DN100 pipelines), explosion-proof type, and 4-20mA/RS485 connection to DCS.

- Effect: 3 consecutive years of trouble-free operation, resistance to corrosion and electromagnetic interference, adaptation to high-temperature and high-pressure working conditions, and long sensor service life.

5. Underground Mining: Drainage and Mineral Processing Slurry Monitoring (Huarui YHL500)

- Scenario: Underground coal mine drainage and mineral processing slurry measurement, requiring explosion-proof performance and installation in narrow spaces.

- Solution: Mining-explosion-proof wall-mounted host with clamp-on sensors, installed away from pumps and valves, and 4-20mA signal connection to PLC.

- Effect: MA certification, adaptation to humid and electromagnetic underground environments, real-time monitoring of drainage and slurry flow, and safety assurance.

Key Points for Selection and Installation

- Clamp-on type: Applicable for DN15~DN6000, clean or general sewage pipelines, no pipe cutting required.

- Insertion type: Applicable for pipelines ≥DN80 with scaling or lining, strong anti-interference capability.

- Installation: Select straight pipe sections (10D upstream and 5D downstream), V/Z installation method matching pipe diameter, shielded wire grounding, and installation away from strong electromagnetic sources.

- Signal: 4-20mA/RS485/pulse output, easy integration into PLC/DCS/environmental monitoring platforms.
