Nominal width DN 50 … 700, 57 … 720 mm / approx. USB (for online measurement and reading of the internal memory)ģ x AA NiMH rechargeable battery / 2100 mAh (at full charge 12h running time) Please note that the meter's measured values depend on the pipe geometry, material and coating the medium type, temperature and speed and the sensor type and measuring method. This ensures traceability to the Physikalisch-Technische Bundesanstalt (PTB) German national standard. Completely portable, running on battery or 120 VAC, easy to install, the Regal RH20 is the perfect tool for flow survey, meter verification, pump performance validation, and other demanding facility management flow monitoring applications. ![]() The reference display of the in-house test stand used by PCE for calibration has a valid DAkkS calibration certificate. Fuel oil, glycol, waste streams, water distribution- Spire’s Regal RH20 flow meter is up to the challenge. This software is sold separately - see accessories for details.Įach PCE-TDS series meter is assembled by PCE Instruments in Germany and and factory-calibrated (without any documentation). The OTT SLD is a stationary unit for continuously measuring flow velocity and water level in rivers, streams, and other open channels with. They measure the velocity of a fluid in a closed pipe and utilize transducers to emit ultrasonic pulses (greater than 20 kHz frequency) from which the flow meter can calculate the average velocity along the path of the beam of ultrasound. The OTT MF pro is a magnetic-inductive flow meter designed for SxS wading rod measurements in smaller rivers and open channels. Note: To transfer data to a computer, SOFT-PCE-TDS software is required. Ultrasonic meters are commonly used for custody transfer and fiscal oil and gas measurement. Portable Digital Ultrasonic Flow Meter with Small & Medium Transducers for Pipes from 0.76 to 27 inch (20 to 700 mm) & from -40☏ to 320☏ (-40☌ to 160☌). ![]() ![]() The transit-time principle requires pipes to be full and have no bubbles and no particles. T2 = run time of the ultrasonic signal against the flow direction T1 = run time of the ultrasonic signal in the flow direction A battery-operated flow meter that measures flow through the pipe wall via the transit time ultrasonic principle. Measurable liquids include: acetate, acetone, alcohol, ammonia, aniline, benzene, butyrate, chloroform, ethanol, ethyl alcohol, ethyl ether, ethylene glycol, freon R 12, petrol, glycerin, glycol, isobutanol, isobutane, isopentane, kerosene, linseed oil, methanol, methyl alcohol, engine oil, diesel oil, olive oil, peanut oil, paraffin oil, pentane, petroleum, 1-propanol, coolant, lubricating oil, silicone oil, transformer oil, trichlorethylene, 1, 1, 1 - trichloroethane, turpentine, distilled water and sea water.Ĭalculation of flow velocity according to the transit-time principle follows the equation:
