Do you need to measure low or intermittent flow rates? Do you need turn down up to 1,000: 1? Bidirectional flow control? Perform fuel injector tests? Valve leak testing? When you need an instantaneous flow profile data control, we recommend using a positive displacement flow meter. We put at your disposal different technologies that fit perfectly your application.
Piston Flow Meters
Piston Meters provide ultra-precise measurement for your lowest flow rate applications. Accuracy, resolution and response rate normally associated with laboratory measurement devices comes in a convenient to use, rugged, industrial-grade sensor.
Compare our guaranteed ±0.2% of reading specification and 2000:1 operating ranges against any other flow meter. Flow rates below 1 cc/min and fluid viscosities from 0.5 to 10,000 cps are all in a day’s work for these high performance meters.
Gear Flow Meters
No other gear meter offers the resolution, accuracy and operating range that comes standard on every of our devices. We offer the industry’s highest resolution output signal and bi-directional measurement capabilities. Superior mechanical performance delivers significantly lower pressure drop versus the competition.
An unchallenged accuracy specification of ±0.3% of reading over a 100:1 turndown and a total operating range of over 200:1 elevates the G-Series to a performance level long desired by metrology professionals. Economical and versatile, these meters are ideal for viscosities from 5 to 10,000 cps.
Helical Flow Meters
Flow measurement of high viscosity fluids is often limited by the high pressure drop that a flow meter adds to the system. However, switching to a larger meter to reduce this pressure loss will result in a corresponding reduction in the resolution of the meter.
The Helica flow meters use a progressive cavity rotor to perform the positive displacement measurement with an accuracy specification of ±0.2% of reading over a 50:1 turndown. The in-line metering elements (rotors) turn smoothly with the flow and greatly reduce the pressure loss. By reducing the pressure loss of the meter, a smaller, faster-spinning meter can be used to generate a high resolution signal, even when fluid viscosities approach 1,000,000 cps.
