Liquid Mass Flow Meter are designed for high-end flow metering applications. They meet performance verification standards from China, the EU, North America, and Russia, offering excellent flow and density measurement performance.
Product Description
A Liquid Mass Flow Meter is a precision instrument used to measure the mass flow rate of a liquid passing through a pipeline, rather than just the volumetric flow rate. It is widely used in industries such as chemical processing, oil and gas, food and beverage, and pharmaceuticals, where accurate mass flow measurement is critical for process control and material balance.
Unlike traditional volumetric flow meters, which are influenced by changes in temperature and pressure, mass flow meters directly measure the mass of the liquid, ensuring high accuracy and reliability under varying operating conditions.
Vibrating Flow Tubes: The meter consists of one or two flow tubes that are set into controlled vibration.
Coriolis Effect Generation: When liquid flows through the vibrating tubes, the fluid’s mass causes a phase shift (twist) due to the Coriolis force.
Phase Shift Detection: Sensors measure this phase shift, which is directly proportional to the mass flow rate.
Calculation & Output: The meter’s electronics process the signals and convert them into a precise mass flow measurement.
· Liquid mass flow and density measurement with accuracy up to ±0.05% for mass flow and ±0.2 kg/m³ for density.
· Capable of measuring extremely small flow rates, ideal for trade settlements and critical process control, with certification for trade exchange
· Stable gas flow measurement
· Reliable measurement of gas-liquid two-phase and multiphase mixed fluids
· Compact design that fits various piping and field conditions, reducing installation space and minimizing pressure loss.
· Cleanable and self-draining design for demanding industry applications
· Can be extended for high-temperature, high-pressure, ultra-high-pressure, cryogenic, and sanitary applications with corrosion-resistant materials
· No need for straight pipe sections for flow conditioning, unaffected by environmental factors, and capable of operating at low temperatures of -40°C.
· Supports a wide range of communication protocols and allows for customizable input/output combinations
· Multiple measurement module options for fluid concentration, composition, and viscosity measurements, with support for bidirectional and batch flow measurements.
· Innovative smart self-diagnostics for long-term stable operation
