DATA SHEET Flow Hach FH950 Portable Flow Meter with Electromagnetic Flow Sensor Now Measures Both Depth and Velocity The FH950 Velocity Meter simplifies set up, displays real time data and trend information, auto-calculates discharge volumes and eliminates the need for manual recording with its convenient USB to PC data download; with no moving parts, the sensor never requires mechanical maintenance. Features and Benefits The lightweight, battery-powered FH950 Velocity Flow Meter was designed to provide accurate velocity measurements while simplifying the entire measurement process in rugged field environments. Multiple user-friendly features designed into the FH950 allow you to quickly and easily determine stream velocities for required discharge measurements, or use the FH950 to calibrate area velocity flow meters, or verify primary devices such as weirs and flumes. User-Friendly Interface Simplifies Programming and Reduces Man-hours by 50% The FH950’s rugged, lightweight and user-friendly design allows for easy set-up, operation and data management. An easy-to-use, menu-driven user interface includes a graphics display that is readable even in bright sunlight. The ability to store and download velocity and depth information within the meter, minimizes field time up to 50%. Discharge calculations are automatically calculated by the meter. Conveniently download collected data to a PC via the USB connection, eliminating the need for labor intensive manual data transfer. Maintenance-Free Electromagnetic Sensor The FH950’s electromagnetic sensor has no moving parts and never requires maintenance, making it one of the lowest maintenance solutions on the market. Turbulent, noisy and low velocities are easily metered. When the sensor is placed in flowing water, its magnetic field creates a voltage that is sensed by electrodes embedded in the sensor. The voltage amplitude, proportional to the water velocity flowing around the sensor, is electronically processed by the smart sensor’s microprocessor and is digitally transmitted through the cable to the portable meter display. See the Difference the FH950 Makes! • Reduce man-hours 50%—the step-by-step user interface simplifies programming, delivers real time data, and downloads direct to PC—allowing a single person to take the readings and eliminating post site visit manual data transfer from log book to PC • Automatically calculates total discharge based on USGS and ISO methods—reduces time to manually calculate and likelihood of errors • Real-time velocity graphed on color display— visualize velocity trends quickly • Color graphic display guides user to the ideal depth measurement position • One of the lowest maintenance solutions on the market— electromagnetic velocity sensor with no moving parts never requires mechanical maintenance • Lightweight, rugged portable meter—only 1.5 pounds • Water resistant electronics • Rechargeable portable meter • Data Storage for up to 10 profiles (metering sites) with 32 stations (vertical profiles) per profile (site) • Easy-to-use, menu-driven interface display remains readable even in bright sunlight • Ideal for use in waters with organic matter; the magnetic inductive measurement principle is not negatively affected by these conditions like acoustics or mechanical meters Applications • • • • • • Streams Rivers Weir/Flume/Flow Meter Calibration Sewers Mining Channels Irrigation Channels DW = drinking water WW = wastewater municipal PW = pure water / power IW = industrial water E = environmental C = collections FB = food and beverage WW IW C
