K24 Flow Meters and Other Meters
HAIBO provides a comprehensive range of flow meters designed for accurate, stable and long-term measurement of fuels, lubricating oils and industrial liquids.
The product portfolio includes digital turbine flow meters, gear flow meters, oval gear (positive displacement) flow meters, mechanical flow meters, and electronic preset flow meters, suitable for low-, medium- and high-viscosity fluids.
HAIBO flow meters are widely used in fuel transfer and dispensing systems, metering and batching equipment, tank truck loading and unloading, industrial fluid management, agriculture, mining, construction machinery, and non-commercial measurement applications.
1. Digital Turbine Flow Meters – Ideal for Low-Viscosity Fluids
Digital turbine flow meters measure flow by detecting the rotational speed of a turbine driven by the liquid. They are especially suitable for clean, low-viscosity fluids, offering fast response, compact design and easy installation.
Typical Products
K24 Digital Turbine Flow Meter
K24-02 Digital Turbine Flow Meter
TEM-XX Series Digital Turbine Flow Meters
K24-HS Series High-Accuracy Digital Turbine Flow Meters
Proven Industry Advantages
Typical accuracy of ±1%, with high-accuracy models up to ±0.5%
Battery-powered operation, ideal for mobile and field applications
Digital display with resettable batch total and cumulative total
Multiple unit options: Liter, Gallon, Quart, Pint, Cubic Meter
Inline installation or mounting behind dispensing nozzles
Housing options in aluminum alloy, reinforced polyamide or stainless steel
Typical Applications
Diesel and gasoline dispensing systems, fuel transfer pumps, urea solution and water measurement, light chemical liquids, mobile fueling units.
Industry Insight: Digital turbine flow meters are widely adopted worldwide for non-custody transfer measurement due to their cost efficiency and ease of use.
2. Gear Flow Meters – Stable Measurement at Low Flow Rates
Gear flow meters operate on a positive displacement principle, delivering excellent stability and repeatability, especially under low-flow conditions.
Typical Products
WGK24 Series Gear Flow Meters
Engineering plastic body versions
Aluminum alloy body versions
Technical Advantages
High repeatability, typically ±0.5%
Measurement independent of flow velocity
Compact structure with low pressure loss
Suitable for clean and stable liquids
Digital display with multiple unit selections
Typical Applications
Lubrication systems, low-flow industrial processes, laboratory fluid measurement, oil and chemical transfer.
3. Oval Gear Flow Meters – Professional Choice for Medium and High Viscosity Fluids
Oval gear flow meters are classic positive displacement flow meters, globally recognized for their high accuracy, excellent repeatability and long-term stability, especially for medium- and high-viscosity liquids.
Product Types
Mechanical Oval Gear Flow Meters
Electronic Oval Gear Flow Meters
Electronic Preset Oval Gear Flow Meters
Core Advantages
Accuracy independent of flow rate
Excellent performance with lubricating oil and heavy oil
Mechanical models require no external power supply
Electronic models support digital display and signal output
Preset models enable precise volume control and overfill prevention
Housing materials available in aluminum alloy, stainless steel and plastic
Typical Applications
Lubricating oil dispensing, industrial oil transfer, chemical batching systems, fuel loading and unloading operations.
Industry Insight: Due to their insensitivity to viscosity changes, oval gear flow meters are widely used by international brands in oil and chemical industries.
4. Mechanical Flow Meters – Reliable Operation without Power Supply
Mechanical flow meters remain a preferred solution where simplicity, durability and independence from electricity are required.
Typical Products
FM-150 Mechanical Oval Gear Flow Meter
800C Series Mechanical Flow Meters
999 Series Mechanical Flow Meters
FM-120 / FM-120L Mechanical Flow Meters
Key Features
Aluminum or plastic-aluminum construction
Mechanical roller-type readout with resettable subtotal
Connection sizes available in 1″, 1.5″ and 2″
Easy installation, calibration and maintenance on site
Designed for non-commercial and internal measurement applications
Typical Applications
Farm fueling systems, mining equipment refueling, construction machinery, portable fuel transfer systems.
5. Electronic Preset Flow Meters – Accurate Batching and Safer Dispensing
Electronic preset flow meters allow users to set a target dispensing volume in advance. Once the preset value is reached, the system automatically stops or controls the flow, significantly improving operational safety and efficiency.
Key Benefits
Improved dispensing accuracy
Reduced risk of overfilling and spillage
Ideal for repetitive dispensing operations
Widely used for fuel, lubricating oil and chemical liquid dispensing
6. Material Options and Fluid Compatibility
To meet diverse operating conditions, HAIBO flow meters are available in multiple materials:
Aluminum Alloy: Diesel, gasoline, kerosene, light oils
