Product Description
2-Channel Ultrasonic Flowmeter
Product Overview
The 2-channel ultrasonic flowmeter with 100 functional menus is a precise and advanced product manufactured in China by Nik Senso Tech for flow measurement of liquids in various industries. This dual-path flowmeter utilizes 4 piezoelectric sensors (2 pairs) installed on opposite sides of the pipe, enabling simultaneous measurement from two independent paths. The key advantage of the 2-channel ultrasonic flowmeter over single-channel models is averaging the outputs from both channels, which significantly increases overall accuracy—especially in large-diameter pipes and asymmetric flow conditions.
Advantages
This flow measurement equipment is sourced directly from the manufacturer in China, ensuring competitive and cost-effective pricing compared to similar products on the market. High build quality and reasonable price make this dual-channel ultrasonic device an ideal choice for water and wastewater treatment, oil, gas, petrochemical industries, and energy monitoring applications. Installation is wall-mounted and it is compatible with both metallic and non-metallic pipes.
Sensor Installation Methods – Clamp-On Type
| Installation Method | Sensor Arrangement | Application | Advantage |
|---|---|---|---|
| V-Path | Sensors on one side of the pipe; signal reflects once | Standard pipes (DN50 to DN400) | Simplest method, good accuracy |
| W-Path | Sensors on one side of the pipe; signal reflects three times | Small pipes (DN15 to DN100) | Extended signal path for higher accuracy |
| Z-Path | Sensors on opposite sides (crosswise); signal passes without reflection | Large pipes (above DN400) or with scaling | Better penetration in weak-signal fluids |
| N-Path | Combination of Z and V methods | Special applications and very large pipes | Maximum accuracy for large diameters |
Sensor Installation Methods – Insertion Type
| Installation Method | Sensor Arrangement | Application | Advantage |
|---|---|---|---|
| Cross | 4 sensors in cross arrangement on both sides of the pipe | Large pipes, asymmetric flow | High accuracy, most common method |
| Parallel | 4 sensors on one side, in sequence | Very large pipes, limited space | Suitable for confined spaces |
| Angled | Sensors at 30–60° angle | Special flow conditions | Signal optimization |
