Premium Flow Meters Providing Precision Measurement for Your Application

Our high-grade flow measurement devices are designed for applications where accuracy and reliability matter most.

You might need to know exactly how much fluid moves through your system for effective process control. Or perhaps you need accurate flow readings for potable water custody transfer billing. Inaccurate readings aren't just inconvenient — they can cost you money, compromise product quality, and may even create compliance risks. Whether you're managing water treatment plants, monitoring steam in power generation, or ensuring precise chemical mixing, unreliable flow readings can lead to inefficient operations and unplanned downtime.

91ÊÓƵ understands flow measurement challenges. With a comprehensive range of flow meters suitable for liquid, gas, and steam applications, we provide the instrumentation you need to operate with confidence.

Flow Meter Types & Applications

Explore a variety of flow meter technologies available at 91ÊÓƵ. From tried and trusted industry stalwarts to new innovation benchmarks, we have a flow meter that's right for you.

Electromagnetic Flow Meters

• Works by generating a magnetic field across a pipe. As conductive fluid passes through, a voltage develops and is measured by electrodes. The voltage is directly proportional to the fluid velocity.
• Accuracy: Generally ±0.2% to ±0.5%
• Benefits: No moving parts, no pressure drop, and can be used for dirty liquids and slurries
• Cannot be used for oils, hydrocarbons, or non-conductive fluids
• Applications: Municipal water, wastewater treatment, chemical processing

Ultrasonic Flow Meters

• Works by transmitting high-frequency sound waves through a pipe and detecting frequency shifts or time differences, which correspond to fluid velocity.
• The transit time technique is used for clean fluids; the Doppler technique is used for fluids containing particles or bubbles.
• Accuracy: Typically ±0.5% to ±2%
• Benefits: Non-intrusive clamp-on ultrasonic options, suitable for large diameter pipes, and portable systems are available
• Applications: Water distribution, HVAC systems, hygienic systems

Coriolis Flow Meters

• Works by vibrating measuring tubes within the meter, and measuring the force induced by the fluid flowing through the tubes (Coriolis force), which is directly related to the mass flow rate of the fluid.
• Accuracy: Typically ±0.05% to ±0.2%
• Benefits: Measures mass and density directly, suitable for high-viscosity, multiphase and non-Newtonian fluids
• Applications: Oil and gas, chemical processing, food and beverage, slurries, custody transfer

Turbine Flow Meters

• Works by placing a rotor within the flow path, and measuring the rotational speed (RPM) of the rotor, which is directly proportional to fluid velocity.
• Accuracy: Typically ±0.5% to ±1.5%
• Benefits: Wide flow range, repeatability, fast response, cost-effective
• Suited to clean, low-viscosity fluids
• Applications: Oil and gas, fuel systems, domestic water measurement

Vortex Flow Meters

• Works by placing an obstruction in the flow stream, and measuring the frequency of vortices downstream of the obstruction, which is directly proportional to the fluid velocity.
• Accuracy: Typically ±0.5% to ±1%
• Benefits: No moving parts, handles high temperatures and pressures, low maintenance
• Versatile measurement solution for clean liquids, gases, and saturated steam
• Applications: Steam systems, chemical processing, HVAC

Differential Pressure (DP) Meters

• Works by placing a restriction (such as an orifice plate) in a pipe, creating a measurable pressure drop across the restriction, which is proportional to the flow rate of the fluid.
• Accuracy: Generally ±0.5% to ±5%
• Benefits: Versatile, cost-effective and industry-proven (refer to ISO 5167)
• Types include orifice plates, Venturi tubes, Pitot tubes, and flow nozzles. Suitable for high temperature and harsh applications, but with limited turndown.
• Applications: Steam, fuel systems, natural gas, process monitoring
