Description

PCE-TDS 100H Ultrasonic Flow Meter
Measures liquid flow velocity in pipes and tubes with a diameter of 57 … 720 mm / ≈ 2 … 28 in

This is a portable handheld clamp-on ultrasonic flow 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, trichlorethylene, 1, 1, 1 – trichloroethane, turpentine, distilled water and sea water.

Calculation of flow velocity according to the transit-time principle follows the equation:

v = measured velocity
T1 = run time of the ultrasonic signal in the flow direction
T2 = run time of the ultrasonic signal against the flow direction
L = length of the ultrasonic wave
α = ultrasonic signal angle to the flow

The transit-time principle requires pipes to be full and have no bubbles and no particles.

Note: To transfer data to a computer, SOFT-PCE-TDS software is required. This software is sold separately – see accessories for details.

Each meter is assembled and calibrated by PCE Instruments in Germany. Therefore, a factory calibration certificate is provided by PCE Germany in the delivery contents of the meter. The certificate includes one measuring point on two different pipes. 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 Bundesanstal (PTB) German national standard. Please note that because the meter’s measured values depend upon the pipe geometry, material and coating; the medium type, temperature and speed; and the sensor type and measuring method, these parameters are listed on the supplied certificate for maximum traceability.
