4.7Enclosure
IP65:
IP68: only available for remote-type sensor with neoprene or polyurethane liner, not including flameproof model.
4.8Flameproof Standard
DN15-DN600 compact-type: md II BT4
DN15-DN1600 remote-type: sensor and converter both installed in dangerous area: md II BT4.
DN15-DN1600 remote-type: sensor installed in dangerous area and converter installed in safe area: md II BT4
4.9Connection Cable
Special cable is needed to connect the sensor and the converter for remote-type flowmeter. The cable length should not exceed 100 meters. A 10-meter cable is supplied free of charge and the rest is to be ordered.
4.10General Specification of Converter
Power supply: AC 85-265V, 45-63Hz, ≤20W; DC 11-40V
Converter display and operation: four keys are available to set all parameters. External handheld or PC can be used to do the configuration. High resolution LCD display with backlight, empty pipe detection and self-diagnostic function are equipped in the converter.
Digital communication: RS485, RS232, MODBUS,REMOTE
Output Signals:
- Current output: fully-isolated, 4-20mA/0-10mA
load resistance: 0-10mA: 0-1.5KΩ; 4-20mA: 0-750Ω.
- Frequency output: bidirectional flow output. Frequency output is proportional to the flow percentage of the full range. The converter provides fully isolated transistor open collector frequency output ranged from 1 to 5000 Hz. The external DC power supply should not exceed 35V and maximum collector current is 250mA.
- Pulse output: bidirectional flow output. The converter can output up to 5000cp/s pulse series, which is dedicated to external totalization. Pulse factor is defined as volume or mass per pulse. It can be set to 0.001L/p, 0.01L/p, 0.1L/p, 1L/p, 2L/p, 5L/p, 10L/p, 100L/p, 1m3/p, 10 m3/p, 100 m3/p or 1000 m3/p. Pulse width is selectable from auto, 10ms, 20ms, 50ms, 100ms, 150ms, 200ms, 250ms, 300ms, 350ms and 400ms. Photo-coupler isolated transistor open collector circuit is used for pulse output. The external DC power supply should not exceed 35V and maximum collector current is 250mA.
- Flow direction indication: The converter is capable of measuring both forward and reverse flow and recognizing its direction. The converter outputs 0V low level for forward flow, while +12V high level for reverse flow.
- Alarm output: Two channels of photo-coupler isolated open collector circuit are used for alarm signal output. There are two alarm outputs: high limit alarm and low limit alarm. The external DC power supply should not exceed 35V and maximum collector current is 250mA.
- Damping constant: Damping time is selectable from 0.2 to 100s.
