In the tubular ultrasonic flow meter, both the main unit and the sensors are installed on the measurement pipeline. This product makes use of multi-pulse technology, digital signal processing techniques, and error correction methods, which enable it to function better in industrial environments. It eliminates the errors that can occur during the installation of clamp-type or insert-type sensors due to human factors or issues related to the pipeline. It features high accuracy, no pressure loss, and simple installation. Its networking capability is suitable for managing large-scale water supply systems as well as monitoring water usage; wireless data transmission can be used for automatic reading of measurements anywhere there is a GSM network signal.

产品特点Product features

• Various power supply options are available, eliminating the need for instrument calibration on site.

• It features a self-diagnosis function that indicates whether the current operating status is normal.

• The nominal diameter can range from DN15 to 1000 mm, and there are various options available for the material of the pipe body.

• It features flange mounting, has no mechanical moving parts, is not prone to damage, requires no maintenance, offers high measurement accuracy, stable operation, and high reliability.

• A temperature sensor is used to measure the temperature of the water flowing in and out of the heating (cooling) pipelines, allowing for real-time monitoring of the heat (cooling) output; this enables the measurement of the amount of heat (cooling) supplied.

• It features a variety of output options; data can be transmitted via the RS485 bus over distances of several kilometers. The MODBUS protocol makes networking straightforward, and it enables timely monitoring of the device’s operation, thus meeting the various needs of different users.

技术参数Technical parameters

测量精度Measurement accuracy	± 1%± 1%
测量范围Measurement range	0～±10m/S
数据接口Data interface	The RS485 serial interface is isolated, allowing the flow meter to be upgraded using a PC; it supports protocols such as Modbus.
数据记录Data recording	It automatically remembers the positive/negative/net cumulative values for the past 512 days, 128 months, and the past 10 days; it also stores the data related to the first 30 instances of power on/off as well as the flow rate, and allows for automatic or manual adjustment of this flow rate.
屏幕显示Screen display	It can be connected to a 2×10 backlit Chinese character LCD or a 2×20 character Western-language LCD, and supports three languages: Chinese, English, and Italian.
信号输出Signal output	1路4~20mA电流输出Current output of 4–20 mA on channel 1
	OCT pulse output on channel 1 (pulse width programmable between 6 and 1000 ms; default value is 200 ms)
	1路继电器输出Channel 1 relay output
信号输入Signal input	3 analog inputs of 4–20 mA type, with a precision of 0.1%; they can be used to acquire signals such as temperature, pressure, and liquid level. They can also be connected to three-wire PT100 platinum resistors for heat measurement.
