CIXIFM Oil Flow Measuring Low Flow Meters
The M12AL model from CIXIFM is engineered for micro to low-flow applications, offering a K factor of 13.5 ml per pulse. It measures 0.3 to 30 L/min and uses PPS gear material with an aluminum housing, making it suitable for low-viscosity liquids such as oils and hydraulic fluids. Its design supports customization and asserts a factory-direct price with no minimum order quantity. This meter emphasizes compact form without sacrificing reliability, ideal for OEMs and maintenance teams needing precise flow data for small systems.
CIXIFM Mirco Flow Meter (CX-M9SS)
This sanitary flow meter uses SS316L both for the gear and housing, with a K factor of 2.5 ml per pulse and a flow range of 6 to 600 L/H. It is designed for low-viscosity and chemical liquids and is suitable for food-grade fluids like milk and fruit juice, as well as pharmaceutical liquids. The CX-M9SS emphasizes hygienic design, fine workmanship, and customization options, with no MOQ. It is a strong choice for industries requiring sanitary compliance and accurate measurement in a compact package.
Turbine Flow Meter 3/4″ (BAYM)
The 3/4″ BAYM turbine meter covers flow ranges from 10 to 100 L/Min and up to 40–280 L/Min for larger variants. With aluminum housing and a robust 300 PSI (21 bar) pressure rating, this meter is suitable for kerosene, oil, methanol, and diesel flows. An LCD display provides immediate readouts, and the device can operate in a wide temperature range from -25°C to 121°C. It is available in BSPT/NPT configurations, balancing affordability with dependable accuracy for mid-range monitoring tasks.
Turbine Flow Meter 1″ (BAYM)
The BAYM 1″ turbine meter expands the same turbine technology to a larger size, delivering 10–100 L/Min for 3/4″ options and 40–280 L/Min for 1.5″ variants. It shares the robust aluminum body, 300 PSI pressure rating, and compact dimensions for easy installation in pipelines. This model emphasizes modularity and versatility, making it suitable for automotive fluids, fuels, and industrial liquids where reliability and repeatable readings are essential.
Flow Vis 1.5″ FV-C-15
The FlowVis FV-C-15 offers installation flexibility with horizontal, vertical, or upside-down mounting. It features a clear, easy-to-read GPM scale with velocity point indicators, making it useful for systems requiring quick visual confirmation of flow rate. While specifics on materials aren’t listed in detail here, the unit is designed for straightforward installation in a variety of fluid systems and adds a user-friendly display and orientation flexibility that helps with routine monitoring tasks.
CIXIFM Sanitary 33.5 ml/P (M25SS)
This sanitary meter uses a 33.5 ml per pulse K factor with a flow range of 0.5 to 100 L/min. Built from SS316L, it is suitable for sanitary and food-grade applications, including milk, juice, and pharmaceutical liquids. It emphasizes hygienic design and precise meeting of sanitary standards while maintaining robust performance for clean-in-place environments. Like other CIXIFM products, it targets a no-MOQ approach for customization and scale.
Buying Guide: Key Purchase Considerations
- Fluids and viscosity: Choose a meter whose gear and housing materials match the liquids you measure. SS316L and aluminum housings suit different chemical and cleanliness requirements; sanitary models are best for food-grade liquids.
- Flow range and accuracy: Verify the operational flow range matches your process. Look for specified accuracy (often ±1%) and repeatability to ensure consistent measurement across runs.
- K factor compatibility: The K factor determines pulses per unit volume. Ensure the meter’s K factor aligns with your data acquisition system for precise readouts and easy integration with existing controllers.
- Installation orientation: Some meters support horizontal, vertical, or inverted mounting. Choose based on available space and piping layouts to minimize installation constraints and maintenance access.
- Materials and hygiene: For beverages, pharmaceuticals, or other sanitary liquids, prefer sanitary models with SS316L gears and housings. For oil and hydraulic fluids, aluminum housings offer light weight and cost effectiveness.
- Customization and MOQ: If you need a specific K factor, flow range, or port size, confirm customization options and whether there is a minimum order quantity to avoid supply delays.
- Warranty and support: Verify after-sales support, calibration options, and warranty terms. A supplier offering direct factory pricing plus customization can help reduce total ownership costs.
- Maintenance considerations: Sanitary meters may require CIP compatibility. Consider cleaning requirements and ease of disassembly when selecting a model for fluid processing environments.
Comparative Considerations Across Models
- Low-flow precision: Models like the CIXIFM M12AL offer strong low-end performance for mini systems, while the CX-M9SS targets sanitary, food-grade contexts with a mid-range flow window.
- Material choices: SS316L units provide chemical resistance and food-safety compliance, whereas aluminum housings are common for budget-friendly applications and rugged environments with less chemical exposure.
- Industrial vs. sanitary use: For process lines handling oils or hydraulic fluids, industrial meters with robust housings are preferred. For beverage or pharmaceutical processes, sanitary designs reduce contamination risk.
- Display and integration: Some meters ship with LCD readouts and battery power, which aids on-the-spot monitoring. Others emphasize compact physical footprints with higher customization potential for OEM deployment.
