Page 28: Functional Description
The NivuFlow 650 is used in partly and fully filled pipes, channels and water bodies of various geometries and dimensions. The device types TR and TZ can be equipped with controller functions in the form of a 3-step controller to drive slide valves or other actuators at extra charge.
Page 29: Functional Principle
There is no measurable flow available. The NivuFlow 650 works with both clamp-on sensors and wetted sensors. The clamp-on sen- sors are installed on the outside of the pipe. In this case the transit time through the pipe wall is calculated and considered.
Page 30: Flow Calculation
Instruction Manual NivuFlow 650 The more paths are used in the asymmetrical or disturbed profile and distributed in the flow cross-section, the more accurately the flow can be determined. Sensor 1, path 1 Sensor 2, path 1 Sensor 1, path 2 Sensor 2, path 2 Pipe diameter (at sensor installation in an angle of 45°)
Page 31: Installation And Connection
NivuFlow 650 Type E0 not suitable for installation in NIVUS field enclosure It is not possible to install a NivuFlow 650 Type E0 in a NIVUS field enclosure unless the transmitter is converted to a Type E1 unit. The conversion and the modification of connec- tions can be carried out by NIVUS.
Page 32: Choosing The Installation Place
Make sure that any existing disconnectors (power switch) remain easily accessible during installation. The measurement transmitter can also be installed in field enclosures or similar. NivuFlow 650 is not suitable to be installed directly on site without protective measures due to protection degree.
Page 33: Field Enclosure Fastening And Preparing Electric Installation
The fastening material is not part of the standard delivery but should be specified and chosen individually depending on the place of installation. The NIVUS field enclosure can be installed permanently once the appropriate place of installa- tion has been chosen. A basic condition is safe, durable and stable installation.
Page 34 Readability may be strongly impai- red due to the changes to the protective film. New clear view covers can be purchased from NIVUS for an extra charge and can be easily replaced by the user.

Page 47: Connection To/Via Extension Module Nfe
To implement volume regulation it is necessary to have a NivuFlow 650 Type TR or TZ trans- mitter available. Other types are not suitable since they do not have enough inputs and outputs to drive control slide valves or are not equipped with the corresponding software for controller functions.
Page 48 Use a knife gate valve or a pipe slide valve electric control actuator and 3-step control as control element. Slides with analog control signals cannot be driven.

Activating only one message may lead to disturbances during regulator operation.
Page 51: Overvoltage Protection Measures
Since comprehensive knowledge in control technology is required to correctly program the regulator, more detailed explanations are not needed here. In case of doubt contact the NIVUS commissioning service. 24 Overvoltage Protection Measures Transmitters and their terminal connections should, where the risk demands it, be protected against potential voltages surges (such as lightning strikes in transmission lines) by additional overvoltage protection measures.
Page 52: Overvoltage Protection For Power Supply
NivuFlow 650 24.1 Overvoltage Protection for Power Supply NIVUS recommends type EnerPro 220Tr surge arrestors (for a 100-240 V AC power system) and EnerPro 24Tr (for 24 V DC power supply) for the mains supply. Observe the connection direction Observe the non-reversed connection (p-side to transmitter) as well as a correct, straight wiring supply.
Page 53: Overvoltage Protection For Ma-Inputs/Outputs
Installation and Connection 24.2 Overvoltage Protection for mA-Inputs/Outputs NIVUS recommends type DataPro 2x1 24/24 Tr surge arrestors for mA-inputs and mA-outputs. Observe the connection direction Observe the non-reversed connection (p-side to transmitter) as well as a correct, straight wiring supply. Ground (earth) must lead to the unprotected side.
Page 54: Overvoltage Protection For (Transit Time) Sensor Connectors
Overvoltage protection for (transit time) sensor connectors 24.4.1 Basic protection - equipotential bonding cable NIVUS recommends that an equipotential bonding cable is used to connect the sensor enclo- sure to the control cabinet/transmitter ground as a basic protection measure for the transit time sensors’...
Page 55 The “EnerPro” overvoltage protector may also be installed inside the control cabinet, but the separate earth connector “G” must be retained. The combination with “P” or “C” is very risky in the event of overvoltage. NIVUS recommends that the earth connectors are separated to guard against overvoltages.
Page 56 Instruction Manual NivuFlow 650 All other input/output signals and input/output voltages leaving the control cabinet must also be considered in relation to overvoltages. In most cases, there is no galvanic isolation and compensating currents can flow. In applications particularly at risk of overvoltage, an additional low-capacitance isolating transformer can further reduce the sensitivity to overvoltage events.
Page 57 Installation and Connection Do not reverse protected (p) and unprotected sides of overvoltage protection Fig. 24-8 Modified overvoltage protection 3. Proceed with the overvoltage protection as described in Sect. “24.4.2 Extended protection - overvoltage protection “SonicPro T”” where the top terminals are used for further connection to the transmitter.

Instruction Manual NivuFlow 650 32.5 Setting parameters in Inputs and Outputs (analog and digital) Menu This menu is to define the function of the analog as well as digital inputs and outputs. Other parameters such as measurement and output spans, offsets, limit values, error reactions etc.
Page 99: Analog Outputs
Setting Parameters Fig. 32-16 Analog inputs: Activation / Ext. Reading / Flow Currently the analog inputs can be used for external readings (such as temperature in °C) and for flow measurement. The transmitter hence can be utilised as an extra data logger for readings from other systems.
