    • TDS 100H
    • This is a portable handheld clamp-on ultrasonic flow meter or HVAC meter used for non-invasive, unobstructed, and highly accurate measurements of the flow velocity of liquids in metal, plastic, and rubber pipes and tubes with a diameter of 57 … 720 mm / approx. 2 … 28 in. Ideal for use in oil and gas, water and wastewater, chemical, food and beverage, pharmaceutical, metals and mining, pulp and paper, power and heating, ventilation, air conditioning, and refrigeration (HVACR) industries, this ultrasonic flow meter features user-friendly velcro-strap clamps that allow for quick and easy repositioning of the electroacoustic transducers.
    • 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, trichloroethylene, 1, 1, 1 – trichloroethane, turpentine, distilled water, and seawater.
    • Each PCE-TDS series meter is assembled by PCE Instruments in Germany and factory-calibrated (without any documentation). The reference display of the in-house test stand used by PCE for calibration has a valid DAkkS calibration certificate. This ensures traceability to the Physikalisch-Technische Bundesanstalt (PTB) German national standard. 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.
