Chapter One Product Introduction
The radar flowmeter HFTF-LL100 is a fully automatic flowmeter and RTU collection communication function based on microwave technology. It combines the collected values of the radar level gauge and flow rate with the hydrodynamic model flow algorithm to realize the calculation of cross-sectional flow and cumulative flow. Water level, flow velocity measurement, flow measurement, RTU collection, storage, transmission, and 2G/3G/4G/LoRa communication functions are widely applicable to the current water conservancy and hydrological project flow monitoring, flow monitoring, etc.

Chapter 2 Installation
2.1 Overview
The equipment must be installed correctly to achieve the designed function. Usually the equipment installation must be carried out under the guidance of qualified engineers approved by the company.
2.2 Unpacking
For safe transportation, the equipment usually needs reasonable packaging. When you open the box, please keep the packaging materials so that you can use it when you need to transport it in the future.
The equipment includes the following components:
² 1 device host
² 1 bracket, 8 round head screws (with spring washer and flat washer)
² One CD with instruction manual
² 2 5m aviation plug connection lines
² 1 4G antenna
² 1 LoRa antenna (optional)
² Warranty card
² Certificate of conformity (optional)
2.3 Installation
Dimensions:
The device is encapsulated in a metal case, and there are 4 fixed holes on both sides, which are convenient for users to adjust the angle. Two elliptical grooves are opened on the bracket. U-shaped bolts can be used to fix the device. See the figure below for specific dimensions. (Unit: mm)
Antenna and SIM card installation:
The antenna interface of the device is an SMA female socket. Screw the SMA male head of the matching antenna to the antenna interface of the device, and make sure
Keep the screw tight so as not to affect the signal quality.
When installing or removing the SIM/UIM card, first use a pointed object to gently hold the card eject button (the small round dot on the left side of the SIM/UIM),
The SIM/UIM card holder can be ejected. When installing the SIM/UIM card, put the SIM/UIM card into the card holder first, and make sure that the SIM/UIM
The metal contact surface of the card faces outwards, and then insert the SIM/UIM card sleeve into the drawer and make sure that it is inserted in place.
