Low Pressure Mechanical Flowmeter

The Parker Loflow Series comprises a wide range of inline mechanical flow measurement devices that are designed for low-flow, low-pressure applications. The flowmeters are non-intrusive (i.e., do not obstruct flow) and serve as a low-cost solution for visually verifying small measurements of flow with an accurate reading. Common applications include pharmaceutical manufacturing systems, hospital equipment, swimming pools, water treatment systems,  

Loflow flowmeters are highly simplistic and versatile devices that utilize the tried and tested principle of variable area flow measurement. The meters work in a vertical plane and feature an internal piston / sphere  inside a calibrated tapered bore, which moves as flow rate increases, opening a larger area to pass flowing air, water or hydraulic oil. The design provides users with a direct visual indication of flow rate and serves as a highly reliable method of measuring flow in low-pressure fluid systems. 

Multiple Loflow meters are available to meet the unique fluid flow requirements of customers’ systems, with flow rates range from 0.01 – 22 L/min (0.0026 – 5.8 GPM) and a maximum allowable working pressure of 10 bar (145 psi). All LoFlow devices are calibrated for both oil and water and feature accuracy and repeatability of +-2% full scale defection (FSD) and +-1% FSD, respectively. The meters are relatively insensitive to viscosity changes.
