威仕VSE齒輪高精度流量計VSI 2/1 GRO12V 42R11/5是德國VSE公司研發(fā)的一款容積式流量測量儀表，采用高精度齒輪嚙合結(jié)構(gòu)，適用于各類工業(yè)流體的精密計量。其核心特點包括：測量精度高（典型±0.1%讀數(shù)）、重復(fù)性好（±0.03%）、壓力損失小、對流體粘度變化不敏感，廣泛應(yīng)用于液壓系統(tǒng)、潤滑系統(tǒng)、燃油計量等工業(yè)場景

工作原理

容積式測量原理

該流量計基于容積式測量原理，通過測量流體在單位時間內(nèi)通過固定容積的次數(shù)來計算流量。核心部件為一對相互嚙合的精密齒輪（主動齒輪和從動齒輪），當(dāng)流體進(jìn)入流量計進(jìn)口時，在壓差作用下推動齒輪旋轉(zhuǎn)，齒輪每旋轉(zhuǎn)一周，會排出固定體積的流體（即“排量"），排量與齒輪轉(zhuǎn)速的乘積即為瞬時流量。

The VSE VSI 2/1 GRO12V 42R11/5 is a volumetric flow meter developed by Germany's VSE company, featuring a high-precision gear meshing mechanism designed for accurate measurement of various industrial fluids. Its key advantages include: exceptional measurement accuracy (typical reading accuracy of ±0.1%), excellent repeatability (±0.03%), minimal pressure loss, and insensitivity to fluid viscosity variations. It finds extensive applications in hydraulic systems, lubrication systems, fuel measurement, and other industrial scenarios. Operating Principle: Based on the volumetric measurement principle, this flow meter calculates flow rate by counting the number of times fluid passes through a fixed volume per unit time. Its core components consist of a pair of precision gears (a driving gear and a driven gear) that mesh together. When fluid enters the inlet, the pressure difference drives the gears to rotate; each full rotation discharges a fixed volume of fluid ("displacement"), and the product of this displacement and the gear's rotational speed determines the instantaneous flow rate.

Structural Composition and Component Names | Functional Description---|---Measurement Chamber: House the gear set, forming a sealed measurement space to ensure precise fluid distribution. Gear Set: High-precision meshing gears (typically made of hardened steel or ceramic) that discharge a fixed volume of fluid during rotation. Shaft Seal: Prevents fluid leakage using mechanical or lip seals, suitable for high-pressure applications. Signal Generator: Converts gear speed into electrical signals (e.g., pulse signals) via magnetic/electromagnetic induction or photoelectric sensors. Housing: Protects internal components under system pressure; materials include aluminum alloy or stainless steel. Signal Conversion Process: Gear rotation drives the magnet mounted on the shaft to rotate synchronously, generating periodic magnetic field variations between the magnet and sensor (e.g., Hall element). The sensor outputs pulse signals proportional to rotational speed, which are captured by a counter/PLC. Flow rate is calculated using the formula: Instantaneous Flow Rate Q (L/min) = Pulse Frequency f (Hz) × Displacement V (L/pulse) × 60. Cumulative Flow Total = Total Pulse Count × Displacement V. Technical Parameters (Example: Model VSI 2/1 GRO12V 42R11/5): -VSI: Product series code representing the high-precision gear flow meter. -2/1: Dimension code specifying inlet/outlet diameters (e.g., G1/2 "or G1/4"). -GRO: Gear type: High-precision spur gear design. -12V: Signal output type: Pulse signal powered by 12V (NPN or PNP). -42R11/5: Displacement code. Technical Specifications: Representative displacement: 42 cm3/r (refer to manufacturer's manual for exact values); Measurement range: 0.1–100 L/min (depending on displacement); Operating pressure: Up to 350 bar (high-pressure model); Media temperature: -20°C to 120°C (standard model); Viscosity range: 1–10,000 cSt; Output signals: Pulse (5–24 V DC), 4–20 mA (optional). Application Scenarios: 1. Hydraulic System Flow Monitoring: Used in construction machinery and injection molding machines to monitor hydraulic oil flow in real-time, ensuring proper system pressure-flow matching and preventing overload or leakage. 2. Flow Closed-Loop Control During Mold Closure/Plastic Injection in Injection Molding Machines. 3. Flow Distribution Optimization in Excavator Hydraulic Circuits. 4. Precision Lubricant Dosage: Accurately measures lubricant injection volumes in large equipment lubrication systems (e.g., wind turbine gearboxes, rolling mills), preventing equipment wear due to insufficient lubrication. Suitable for high-viscosity lubricants (e.g., 460# gear oil), offering high long-term operational stability and extended maintenance intervals. 5. Fuel/Chemical Fluid Measurement: Used for batch dosing or continuous flow monitoring in fuel transportation and coating formulation. 6. Laboratory and Research Applications: Serves as a standard flow meter for laboratory calibration and fluid property studies (e.g., university fluid mechanics platforms). 7. Instrument Calibration: Third-party calibration services for measurement devices. Installation and Maintenance Requirements: -Install straight pipe sections at both inlet and outlet (10D upstream and 5D downstream, where D represents pipe diameter) to avoid vortex effects. -Ensure horizontal installation of gear shafts. To reduce bearing wear, the medium flow direction must align with the arrow markings on the housing; reverse installation is prohibited. The system should be positioned away from strong electromagnetic interference sources. Signal cables require shielding treatment. Maintenance guidelines: Regularly inspect filters to prevent impurities from entering the measurement chamber (a 100-mesh or higher filter is recommended). When handling corrosive media, use a stainless steel housing and gears. After prolonged shutdown, completely vent air from the measurement chamber before restarting. Calibration should be performed annually using a standard flow meter. Common faults and troubleshooting: Possible causes: Damaged output signal sensor, loose wiring, gear jamming; Solutions: Check wiring, replace sensor, disassemble and clean gears. Large measurement errors: Gear wear, medium viscosity exceeding limits, reverse installation; Replace gear set, verify medium parameters, correct installation orientation. Abnormal pressure loss: Filter clogging or incomplete opening of inlet/outlet valves; Clean filters and inspect pipeline valve conditions. The Wes VSE Gear High-Precision Flow Meter (VSI 2/1 GRO12V 42R11/5) demonstrates extensive applicability in industrial fluid measurement due to its high precision and reliability. By understanding its volumetric measurement principle, technical specifications, and installation/maintenance requirements, precise flow monitoring can be achieved in hydraulic, lubrication, and chemical applications, providing data support for efficient equipment operation and process optimization. Select appropriate models based on specific operating conditions and strictly adhere to installation protocols to maximize performance advantages.
