Digital flow meter for heating ventilation air conditioning
Item No.:DG-EFM004
MOQ:1 pc
Application:
√ Central air-conditioning
√ Heating industry
√ Heat exchanger unit
Advantages:
√ 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
