![]() (frequency of rotation) is fed through a second device to provide a reading asĪ turbine flow meter is straightforward to Velocity of the water flowing through the turbine flow meter. The velocity (speed) of the blade rotation is directly related to the The turbine flow meter works mechanicallyīy allowing the water flowing through the pipe to rotate a free-spinning Solution, water, sewage, corrosive liquid and fluid flow of mud, pulp, pulp,Įtc,or used as industrial water meter, But it cannot measure the flow of gas, steam and pure water.ĭigtal Magnetic water flow meter standard with pulseĭigital Liquid Turbine Flow Meter to Measure Water Measured flow are linear, the accuracy is high, and the conductivity can be Industrial pipe diameter range is wide, up to 3m, the output signal and the Maximum flow to the minimum flow is generally more than 20: 1.The applicable TheĪdvantage of the electromagnetic flowmeter is that the pressure loss isĮxtremely small, and the measurable flow range is large. That measures flow according to Faraday's law of electromagnetic induction. The output from the digital water flow meterĬould be 4-20mA analog output, pulse or frequency output, the digitalĬommunication could be HART,RS485 or Profibus-DP.Įlectronic magnetic flow meter to measure Water – 20:1 means the flow meter can accurately measure down to 1/20 th of the maximum flow. What is turndown ratio? The turndown ratio reflects the range the flow meter can accurately measure the ![]() Indicates quality measurement over a range of different conditions. The repeatability of a digital flow meter is the ability to precisely measure the same volume of water under the sameĬonditions of temperature, pressure, and flow. Meter shows as a percentage showing how the volume of water measured by a flow Meters for measuring water: Each type works differently with advantages and disadvantages.īelow we explain some Knowledge of flow meter: An accurate measure of the amount of water used comes See Accessories.Measurement of water flows both for drinking water, irrigation, and removal ofĭirty water, RO water, condensate water, sewage water or water use in NOTE: Additional Standard and High Temperature Transducer Sets are available. ![]() Housing Material: ABS plastic with aluminum alloy protective carrying case Totalizer/Calibration: 7-digit totals for net, positive and negative flow respectively press-to-go for calibration Power: 3 "AAA" NiMH built-in batteries (included) with 100 to 240 VAC charger, fully charged lasts over 10 hrs.ĭata Logger: Built-in, stores over 2000 lines of data Access code needs unlocking.ĭisplay: 4 x 16 English letters, 4 x 8 Chinese charactersĬommunications: RS232C (baud rate from 75 to 115,200 bps) Security: Setup values modification lockout. Pipe Material: All metals, most plastics and fiberglass (Liner allowed) Liquid Types: Most liquids including clean water, sea water, waste water, chemical liquids, oil, crude oil, alcohol, beer, and more Totalizer: 7-digit totals for positive, negative and net flow Rate Units (User Configured): Meter, feet, cubic meter, cubic feet, USA gallon, liter, oil barrel, USA liquid barrel, imperial liquid barrel, million USA gallons Pipe Size: DN 15 to 100 mm (0.75 to 4") standard Operating Temperature: Meter, -20 to 60C (- 8 to 140F) With High Temp Transducers: 0 to 160☌ (32 to 320☏) Standard Transducers: 0 to 90☌ (32 to 194☏) Response Time: 0 to 999 seconds (user configured) Transducers for larger pipe sizes and extended temperature ranges are available in the Accessories Section for an additional charge.Īccuracy: ☑% of reading at rates >(0.2m/s) 0.6 ft/s ![]() Standard Clamp on Transducers for Pipe Sizes 3/4" to 4"ġ ea. The instrument will also operate over a wide range of fluid temperatures.Ģ ea. Using ultrasonic transit time techniques, the FDT-25 is controlled by a micro-processor system which contains a wide range of data that enables it to be used with pipes with an outside diameter ranging from 15mm up to 6000mm (depending on model) and constructed of almost any material. Description The FDT-25 handheld ultrasonic flowmeter is designed to work with clamp-on transducers to enable the flow of a liquid within a closed pipe to be measured accurately without needing to insert any mechanical parts through the pipe wall or protrude into the flow system.
