Modular Ultrasonic Flowmeter Application Cases

Modular Ultrasonic Flowmeter Application Cases

Modular ultrasonic flowmeters adopt a sensor + transmitter module + communication/display module combination, which is adaptable to multiple working conditions and easy to expand. The following are 5 typical application cases highlighting the modular advantages and actual benefits.

I. Municipal Water Supply Network Leakage Monitoring (Clamp-on Module + LoRa Wireless Module)

- Scenario: DN2000 tap water trunk pipeline requiring non-stop installation and remote data upload.

- Solution: Clamp-on transducer module + time-difference method transmitter module + LoRa wireless transmission module with IP68 protection, supporting 4-20mA and RS485.

- Effect: The leakage rate decreased from 15% to 9%, saving 12 million tons of water annually; modules can be replaced quickly, reducing maintenance time by 80%.

II. Chemical Circulating Water Cooling System (Insertion Module + Explosion-Proof Module)

- Scenario: 5000m³/h circulating water under high temperature (80℃), requiring explosion protection and real-time optimization of water flow distribution.

- Solution: Insertion-type sensor module + Doppler method transmitter module + Ex d IIC T6 explosion-proof module with temperature compensation function.

- Effect: Cooling efficiency increased by 10%, saving over 250,000 m³ of water annually; modules support hot swapping, enabling fault recovery within less than 30 minutes.

III. Semiconductor Ultrapure Water Preparation (High-Precision Module + Temperature Compensation Module)

- Scenario: Reverse osmosis (RO) membrane inlet water with low flow rate (0.2m/s) and high-precision requirements, needing linkage with the RO system.

- Solution: Dual-channel time-difference module + high-precision signal processing module + temperature compensation module, equipped with PROFIBUS-DP communication.

- Effect: Ultrapure water preparation efficiency improved by 18%, reducing wastewater discharge by 250,000 m³ annually; module-level calibration is available without returning the whole device to the factory.

IV. Sewage Treatment Plant Inlet Monitoring and Chemical Dosing Linkage (Doppler Module + Alarm Module)

- Scenario: Inlet channels with high suspended solids content, requiring real-time flow measurement + over-standard early warning and linkage with the chemical dosing system.

- Solution: Doppler sensor module + transmitter module + abnormal flow alarm module, with 4-20mA output linked to the PLC system.

- Effect: The number of SS over-standard incidents reduced from 8 times to 1 time per month, improving treatment stability by 35%; modules can be combined on demand to adapt to different working conditions.

V. Thermal Energy Measurement of Condensate Water in Power Plants (Split Module + Heat Calculation Module)

- Scenario: 120℃ condensate water requiring synchronous measurement of flow rate and temperature to achieve accurate thermal energy metering.

- Solution: Split-type sensor module + time-difference method transmitter module + heat calculation module, with pressure resistance of PN40 and made of 316L stainless steel.

- Effect: Power generation coal consumption reduced by 2%, and heat settlement error decreased from ±4% to ±1.5%; sensors and transmitter modules can be installed remotely to adapt to high-temperature environments.

Summary of Core Advantages

- Flexible Installation: Clamp-on/insertion modules meet the needs of non-stop water operation, high precision, and other requirements.

- Efficient Maintenance: Hot-swappable modules allow quick replacement in case of faults, reducing downtime losses.

- Convenient Expansion: Communication, explosion-proof, temperature compensation and other modules can be combined on demand to adapt to complex working conditions.
