    Digital flow meter for heating ventilation air conditioning

    Item No.:DG-EFM004

    MOQ:1 pc


    √ Central air-conditioning

    √ Heating industry

    √ Heat exchanger unit


    √  No pressure loss, the measurement is not affected by temperature、pressure and other changes.

    √  A heat insulation device between the transducer and the sensor to prevent the transfer of temperature

    √ Dual current output or double pulse output (positive and negative flow rate respectively) can be selected.

    √ The BACnet communication protocol can be selected.

    √  Excellent low flow rate measurement performance with a 400:1 turndown ratio

    √ The four-electrode structure is suitable for the installation and measurement of various process pipelines, including plastic pipes, fluoride-lined pipes and cement pipes, etc., without the need for another grounding ring.

    √ Reliable empty pipe detection technology

    √  Five-segment nonlinear correction function

    √  Both the power supply and the output circuit adopt reliable lightning protection and surge protection, with high reliability and low fault.

    √  The measurement is stable and the stability is excellent

    Performance parameters

    ■ Accuracy grade: 0.25 and 0.5

    ■ Repeatability: ±0.1% of measured value

    ■ Response time: the maximum 0.3 milliseconds relative to the input change.

    ■ Stability: the stability over 6 months is ±0.1% of measured value 

    ■ Impact of ambient temperature: ±0.25% over operating temperature range
    ■ Impact of the installation location: the installation is not affected as long as the sensor can be fully charged and enough straight sections are ensured before and after

    ■ Startup time: it takes 50 milliseconds to start from zero flow

    ■ Preheating time: it takes 15 minutes from power supply to rated measurement accuracy
