The N1500FT indicator is the ideal device to monitor flow in water and other liquid distribution systems.
Quick and easy to set up via the front keypad, the N1500-FT indicator is compatible with most flow sensor signals including PNP, NPN, dry contact and magnetic pickup. In addition, it has a secondary 4-20mA input and allows simultaneous display of flow and pressure. The N1500FT indicator has a keyboard programmable scale, configurable decimal point, 24Vdc power supply for the flow sensor, a very easy to read display, a switching power supply and up to 4 alarm relays, retransmission of the measured variable in pulse mode and 4 to 20mA and RS485 digital communication with Modbus protocol.
Both Analog and Pulse Inputs
The N1500FT allows for two basic input types:
- Instantaneous flow input through a 4-20mA signal. In this case, flow totalization is obtained by integrating instantaneous flow rate. When the 4-20mA input is not used as flow input, it may be used alternatively as auxiliary input. This way it is possible to measure the pressure of a pipeline in addition to the flow for instance.
- Totalized or instantaneous flow input through a pulse signal. Pulse signals may come from sensors or transmitters with NPN, PNP, dry contact or even magnetic pickup outputs.
Both the 4-20mA as well as the pulse input signal a from flow meter may have a scale factor applied to them to the display the flow in engineering units.
The N1500FT may be used with flow meters with non-linear 4-20mA output signals. When the flow rate is read through a 4-20mA input, it is possible to apply a customized linearization composed of 30 input points and 30 output points.
Retransmission of the Measurement Value
The N1500FT has a 4-20mA analog output and NPN pulse output that may be used to retransmit the measured values. The fully scaleable 4-20mA output may be used to retransmit the instantaneous flow rate. The pulse output can be used to retransmit the measured value as a volumetric pulse output or frequency pulse output. The volumetric pulse output may be used regardless of the type of input, while the frequency pulse output is available only for pulse inputs
The N1500FT is available with either two our four alarm relay outputs (model dependent). The alarms can be set for the following alarm types:
- Open Sensor Alarm
- Maximum Value Alarm
- Minimum Value Alarm
- Feeder Function
The feeder function is used to control the flow of the volume of liquid which typically used for storage applications. There is a start signal (via either keyboard button or digital input) which triggers a relay to begin the flow. A programmed value is used to deactivate the relay to stop the flow when the specified value is reached.
24Vdc Sensor Excitation
The N1500FT powered by AC power also provide a 24Vdc/50mA output that may be used for powering sensors.
Optional RS485 Modbus Communications
The N1500FT is optionally available with a RS485 serial communication for communicating with a computer or PLC. The communication protocol is MODBUS RTU Protocol which is an industry standard protocol. We also provide FieldChart Lite software, a supervisory and data acquisition software as a free download.
FieldChart Supervisory and Data Acquisition Software (Lite version available as a free download)
FieldChart is a software used for monitor and register data acquired from the N1500FT. It generates real time trends and data lists that can be exported in usable formats like a spread sheet. There are two versions available: FieldChart-Lite and FieldChart-64C. The FieldChart-Lite can read 8 simultaneous channels and it is available for free. FieldChart-64C is an optional purchase that can register up to 64 simultaneous channels.
