Description:

ABTDS-100: Fixed type Clamp-on
Transit-Time Ultrasonic Flowmeter

- State-of-the-art Clamp-on Transit-time technology

Low cost, good performance

Wall-mounted type flowmeters have been CE approved.


Descriptions:                

The Abtds-100 clamp-on ultrasonic flowmeter provides abundant capabilities for accurate liquid flow measurement. The utilization of proprietary ultrasound transmission / receiving, transit-time measurement and ultrasonic signal processing technologies allows our flowmeter to measure liquid flow rate from outside of a pipe reliably and accurately.

The Abtds-100 flowmeter is carefully designed so that its user-interfaces are self-explanatory and the instrument is very easy to operate. The unique clamp-on fixture design makes the installation very simple and no special skills or tools required. Due to the non-intrusive nature of the clamp-on technique, there is no pressure drop, no moving parts, no leaks, no risk of contamination, no risk of corrosion, not pressure dependent, and etc.

The Abtds-100 is wall-mount clamp-on type or fixed-installation clamp-on type. Therefore, it is an ideal choice for long-term deployment for flow measurement and closed-pipe applications, such as liquid process control, water flow measurement (hot/chill water, city water, sea water), sewage and sludge measurement, and measurements of oil (crude/diesel/fuel), chemicals (alcohol, acids, etc.), beverage, and many other liquids.

Features:  

(1).Guaranteed lowest price on the market.
(2).High accuracy. Normally, ±1% When on-site calibration available, ±0.5%.
(3).Wide flow range 0.03 to 105ft/s.
(4).Wide pipe size range (from 1" to 240"). PI type transducer can be made to measure the  min inner diameter of 2mm.
(5).Noninvasive. No pipe disturbance. No moving parts, no pressure drop.
(6).Easy and economical installation. No cutting pipe, non drilling hole.
(7).Suitable for all commonly used pipe materials
(8).Easy to use and set up. Self-explanatory menu programming
(9).Velocity, volumetric and totalized flow
(10).GPRS / GSM networking capability with certain model
(11).Ideal for both clean and opaque liquid flow measurements
