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
