Flow Level Pressure Self-sufficient and Contactless Flow Metering


Nivus’ new mobile NivuFlow Mobile 600 flow transmitter has been developed specifically for long-term measurements in full pipelines. Very high endurance is achieved thanks to energy-efficient algorithms, performance-optimised sensors and high-capacity rechargeable batteries. Utilising a five-minute-cycle for measuring and recording, it is possible to measure for up to one year without battery replacement. Featuring 182.000 storage cycles, the internal data memory is designed for even longer measurement periods. Contactless clamp-on sensors and pipe sensors for direct measurement in the medium are available. Both sensor types share quick and easy mounting without the need to shut down running processes. The clamp-on sensors do not have any medium contact and are clamped onto the pipe outside.


Thanks to the high protection rating of sensors and transmitter (IP68) it is possible to operate the measurement system even under harsh ambient conditions. For example, batteries can be replaced by the operator even during heavy rain. This ensures uninterrupted measurements even for long-term projects.


The transmitter is controlled on site by using smart terminal devices such as smartphones, tablets or notebooks. Connection is set up using a WLAN created by the transmitter itself. No plug-ins or apps need to be installed to operate the system. During poor weather conditions, in strong sunlight or in case of limited access to the measurement site it is hence possible to operate the instrument from protected areas such as service vehicles etc.


Typical NivuFlow Mobile 600 applications are: leakage detection, pump verification, water supply monitoring, monitoring of inlets and outlets conducting cooling water or circulation systems as well as monitoring of process water and service water.

Designed to IP65 standards the Process Atrato ultrasonic flowmeter from Titan Enterprises is built for use in demanding process and control environments.


Durably constructed from 316 stainless steel and PEEK, and incorporating proprietary ultrasonic flowmeter technology, the Process Atrato offers reduced cost of ownership compared to existing flow measurement devices used in the process environment.

Rated for use up to 65°C and 20Bar the compact Process Atrato is available in 4 models operating over flow ranges from 2ml/min to 15litres/min, featuring an accuracy of ±1% over the whole flow range. Each Process Atrato is calibrated with a pre-set ‘K’ factor so all meters of the same flow range are fully interchangeable simplifying assembly and set-up procedures for OEM manufacturers looking to integrate the flowmeter into their process and control set-up.


Using patented technology that enables it to operate accurately over wide flow ranges, the Process Atrato signal processing system permits flow measurement across the whole Reynolds number range allowing both viscous and non-viscous products to be metered.

The FieldLab Weatherproof Outdoor Enclosure replaces paper based pressure chart recorders with a digital solution. Instead of changing charts every week or month these can log for 3 months at a time or longer before data needs to be collected. Users can download data less frequently and have it all stored reliably onboard the FieldLab in a weatherproof enclosure. The frequency of datalogging can be selected using the FieldLab Desktop software then the FieldLab is deployed into the field to collect data until it is collected.

This is an excellent solution for remote locations where setting up a SCADA, satellite or cell based network is either impractical or not cost effective. Especially in areas such as wellheads or gas gathering lines in oil and gas applications where monitoring is needed and access is limited.


This can be quickly deployed for monitoring events such as low water pressure in water distribution, hydrostatic testing or anywhere where pressure needs to be monitored for anywhere from a day to a few months to determine the cause of some problem.


The FieldLab comes in ranges from 5 to 10,000 psi and has a datalogging capability of 2 million data points. The weatherproof enclosure is NEMA 4X and the solar panel and pole mount option allows the unit to be installed permanently.

Ralston Instruments Introduces Long-term Pressure Logging Solution


Pressure Transmitter with Low-power Voltage Output


The PMP71 consumes less power in operation, making it suitable for solar- or battery-powered applications, such as remote wellheads.


Endress+Hauser added a 1-5 VDC Low Power output option to the PMP71 pressure transmitter that draws only 17 milliwatts of power at 9V, making the PMP71 consume less power during operation than any other voltage- output pressure transmitter in the market This low-power draw makes the PMP71 ideally suited for battery- and solar-powered applications, such as remote oil & gas wellheads, offshore platforms or pumping stations where low power consumption is critical.


The PMP71 measures absolute and gauge pressure of gas, steam or liquid and has built-in algorithms to calculate level, volume and mass of liquids. Measuring spans are available in ranges from -6 to +6 psi up to -15 to 10,500


psi. For safe operation at process temperatures up to 752°F, it has a piezo resistive measuring cell and metallic welded process isolating diaphragm.


The PMP71 has ATEX, FM, CSA, NEPSI, IECEx approvals and is suitable for use in up to SIL3 hazardous applications. The voltage output version is available with the CSA C/US XP approval in North America. For More Info, email:
