How to deal with common faults of metal tube float flowmeter?

Project Overview

LZ series metal tube float flowmeter is suitable for measuring liquids and gases. In the design of the measuring tube, a variety of measuring tubes are configured according to different pipeline conditions and special fluid measurement requirements, such as insulation jacket type, damper type, etc. In addition to standard options, special designs can also be made for users, such as high-pressure type, high-temperature type, etc., to meet user requirements to the greatest extent. Here are the solutions to the following problems encountered during use:

The metal tube float flowmeter has no on-site display

1. Check whether the wiring is correct.

2. Check whether the power supply is correct.

3. Reinstall the LCD module and check for incorrect contact.

4. For multi-wire power supply mode, check whether terminals 12 and 13 are connected to an ammeter or are short-circuited.

The alarm of the metal tube float flowmeter is incorrect

1. Check that the steam flowmeter deviation setting d value cannot be too large.

2. In the FUN function, is the logic function correct? HA-A represents upper bound positive logic. LA-A represents lower bound positive logic.

3. Check the alarm value setting size in SU.

4. If the LCD barcode indication is correct and the output does not operate, you can check whether the external power supply and the negative pole of the external power supply are connected to the negative pole of the instrument power supply.

5. The circuit board is faulty, replace the circuit board.

The cumulative pulse output of the metal tube float flowmeter is incorrect

1. Check whether the alarm value of the selected cumulative pulse output is set to zero.

2. The circuit board is faulty, replace the circuit board.
