LCZ-803WF/P type split wall mounted/disc type digital ultrasonic flowmeterDetailed product description：

The LCZ-803WF/P split wall/disc mounted digital ultrasonic flowmeter is an instrument that measures the liquid flow rate inside a closed circular tube based on the principle of "velocity difference method".
This instrument adopts advanced multi pulse technology, signal digital processing technology, and error correction technology, making the instrument more suitable for industrial field environments.
The LCZ-803WF/P split wall/disc mounted digital ultrasonic flowmeter consists of two parts: a converter and an external clamp sensor.

The installation of the sensor is carried out using a dedicated installation fastening device, which binds the sensor to the outside of the pipeline without affecting the fluid flow state. Installation and maintenance do not require water interruption.
Scope of application for external clamp sensors: 20-4000mm
Selection of converters
Transformers are divided into: split machines (wall mounted), integrated machines (assembled on pipelines), and panel mounted machines (embedded on instrument panels or control cabinet panels). Among them, there is a dedicated type of split machine that is matched with explosion-proof sensors. This type of converter is placed in non explosion-proof places and forms a general and intrinsic safety digital ultrasonic flowmeter with explosion-proof sensors.

Installation of sensors

The straight pipe section must meet the following requirements (D is the inner diameter of the pipeline)
The length of the straight pipe section on the upstream side of the sensor shall not be less than 10D, and on the downstream side shall not be less than 5D. D is the inner diameter of the pipeline. If this requirement cannot be met on site, a flow straightener shall be installed on the upstream side to eliminate vortices in the flow, improve the distribution of the velocity field, and enhance the measurement accuracy and stability of the instrument. If the flow velocity of the liquid is low, the distribution of vortices and velocity fields in the flow can also be improved, and the front straight pipe section can be less than 10D. If there are two directional elbows or other flow barriers on the upstream side of the sensor, the front straight pipe section should be greater than 10D.
Construction and installation location
(1) Vertical pipes with upward (or inclined upward) liquid flow are preferred, followed by horizontal pipes, and pipes with downward (or inclined downward) liquid flow should be avoided as much as possible to prevent liquid from not filling the pipe.
(2) Do not choose the installation position at the highest point of the pipeline to prevent abnormal measurement caused by the accumulation of bubbles in the pipeline.
