VTSYIQI Portable Liquid Ultrasonic Flowmeters Digital Ultrasonic Flow Meter With Transducer Measuring Range DN50 to 700mm 1.97 to 27.56in

Product Description

★Main feature---- * 0.5% of linearity* 0.2% of repeatability * Bilingual interface in Chinese and English* 4 flow totalizers * Patent balanced lower-voltage multi-pulse * built-in date totalizers ultrasonic igniting* built-in data-logger * Work properly near transverters* 0.5 second totalizing period * 100 Pico-second resolution of time measurement
★Typical Applications----The TDS-100 flow meter can be virtually applied to a wide range of measurements. The measured pipe ranges 20-6000 mm [0.5 - 200 inch]. A variety of liquid applications can be accommodated: ultra-pure liquids, potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc. Because the instrument and transducers are non-contacting and have no moving parts, the flow meter can not be affected by system pressure, fouling or wear.
★Data Integrity-----All user-inputted configuration values are retained in the built-in non-volatile flash memory that can store them for over 100 years, even if power is lost or turned off. Password protection is provided to avoid inadvertent configuration changes or totalizer resets.
★Built-in Time-Keeper----- A time-keeper is integrated in the flow meter for the index of date totalizing and works as the time base of flow accumulation. It keeps operating as long as the battery’s terminal voltage is over 1.5V. In case of battery failure, the time-keeper will not keep running and it will lose proper time values. The user must re-enter proper time values in case the battery becomes totally exhausted. An improper time value affects no other functions but the date totalizer.
★Product Identification------- Each set of the TDS-100 Series flow meter has a unique product identification or ESN written into the software that can only be modified with a special tool by the manufacturer. In case of any hardware failure, please provide this number which is located on menu window number M61 when contacting the manufacture.

Product Description
Digital Liquid Ultrasonic Flow Meters Flowmeter with TM-1 Transducer Measuring Range DN50 to 700mm 1.97 to 27.56in

Introduction
The TDS-100 ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. The TDS-100 transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other.
