2. Main technical features
The TDS-100 series ultrasonic flowmeter adopts microprocessing technology and ultra large scale integrated circuits. Compared with other ultrasonic flowmeters, it not only has the significant characteristics of "three highs and one low" (high precision, high reliability, high performance, and low price), but also has the following advantages:
(1) 0.2ns direct time difference measurement circuit, 40ps time difference measurement resolution, ensuring that the instrument can achieve 1% linearity and 0.5% repeatability, with a measurement accuracy of 1%.
(2) Low voltage, multi pulse signal dual balanced transmission and reception Haifeng patented technology, anti-interference circuit design, can be used in almost all industrial environments (especially in frequency converter environments).
(3) Full windowed Chinese display, 2 × 20 character LCD display.
(4) Positive and negative bidirectional measurement, capable of measuring positive, negative, net cumulative flow rate, flow velocity, etc.
(5) Shell mold manufacturing, protection level: IP65.
(6) Equipped with a temperature transmitter, heat measurement can be achieved, which can display instantaneous flow rate (m3/h), flow rate (m/s), cumulative flow rate (m3), cumulative heat (GJ), peak flow rate and time, etc.
(7) The machine is equipped with lightning protection components to ensure good operation in minefields, and lightning arresters can also be directly connected to the power supply for better protection.
(8) Complete signal output and flexible networking functions can meet various requirements of different users.
1 Input signal: 5 channels of 4-20mA analog input, with an accuracy of 0.1%, can input other signals such as temperature, pressure, liquid level, etc.
2 output signals: 1 channel 4-20mA or 0-20mA analog current signal; Relay and OCT output; RS-232/485 standard serial interface output; GPRS, PSTN, CAN bus, and GSM short message networking can be utilized.
(9) Complete software design: Accumulated daily, monthly, and yearly functions: can remember the cumulative traffic of the first 64 operating days, the first 64 operating months, any day, any month, or any year in the first 5 operating years, making it easy to query and manage.
(10) Power on/off management function: It can record the first 64 power on/off times and the instantaneous flow at the time of power on/off, protecting all data. Users can choose to automatically or manually replenish the flow to reduce user flow loss.
(11) It has a fault self diagnosis function and can automatically remember whether the working status of the first 64 operating days is normal.
(12) Low power consumption and high reliability; The TDS-100 series uses products from IC manufacturers in its design, with a total power consumption of only 2W.
