While the world is adjusting to the new normal during these uncharted times, there are things that remain rather unchanged. Many essential operations in paper and pulp industry are necessary to keep the world spinning. Mills need to run and meet the growing industry demands and people do not have time to learn and study new, complex systems.

Is there any way to simplify the processes?

Kytola OVAL D2 is a smart device built to independently get the job done. It is designed to monitor oil flow rates measured by Model SR oval gear meters in circulation lubrication systems.

Why is an OVAL D2 panel so successful in the pulp and paper industry?

The answer is SIMPLICITY.

The main strength of this panel is being able to fulfill all your requirements and yet being still so easy to use. Within minutes, the operator can read and adjust the flows going to each individual lubrication point.

Kytola Instruments is known for its long-term experience of designing and manufacturing custom-made flow measuring and monitoring instruments for most industrial branches. Kytola products are precision manufactured to the highest quality standards using state-of-the-art materials and testing systems. The endurance of the products in very harsh industrial environments is unparalleled. But most importantly, operational facility is beneficial in various ways. Operators love the easiness to check the actual flows, adjust it locally, see if there is a “high”, “low” or “low low” flow alarm.

The flow meters have a by-pass valve which allows cleaning or service of the flow meters during production. No need to shut down the machine.

This combination of oval gear meters together with the OVALD2 has proven that the payback time is very short.

Another aspect is that when you regulate the flow very accurately. The lifetime of the bearing lasts significantly longer.

The OVAL D2 measuring station can operate as an independent station, connected to Kytola® KVM Control monitoring software or to customer's DCS or PLC via Modbus RTU (RS-485) or Modbus TCP (Ethernet).

In addition to OVAL D2, Kytola has an option for a small panel:


The KLD Smart (up to 8 points) The Kytola KLD Smart local display unit is designed to monitor, and display flow rates and flow alarms measured by Kytola Oval gear meters or other flow meters with pulse outputs.
As name has it, Kytola KLD Smart incorporates latest monitoring technology combined with an easy-to-use touchscreen interface. Flow rates and alarms are very visual, and settings are fast and easy to manage. The device has a robust painted or stainless steel housing and it is protected by IP class 65.

why choose traditional variable area flow meter 1

By Hans Kos

Reverse osmosis (RO) is a water filtration process where water is forced through a semipermeable membrane by water pressure. RO filtration removes fine particles and dissolved substances (such as salts) from water. Reverse osmosis filtration is widely used to produce drinking water from sea water and to produce high purity water for use in industrial processes.

There are various flowmeters used in reverse osmose installations. The variable area flowmeter is used to visually measure the amount of water going through the tubes. Based on this flow, the installation can be adjusted to optimal functioning.

There is a good reason why Kytola’s model H is used very frequently in the reverse osmosis units.

First of all, Kytola Instruments’ flowmeters stand for the highest quality. The materials used in manufacturing are top notch.

Kytola provides 3 model H flowmeters that can cover almost all your needs.

• With 1 size (model HV) but different floats and tubes you can measure from 0.05 to 8 GPM water
• With 1 size (model HK) but different floats you can measure from 1.5 to 20 GPM water
• With 1 size (model HT) but different floats you can measure from 3 to 100 GPM water

Because Kytola uses all kinds of different designed and calibrated floats, you can switch out the flowmeter to a larger or smaller size without changing the tubing. This saves a lot of time in the design. Instead of having to glue expansion sockets to fit the larger flowmeter.

Kytola use on models HT, HK and the larger flows of model HV guide rods where the floats slide up and down the rod. This creates stability.

H meters

Many manufacturers use floats that move freely in the tube. When they go to a larger flow, they often need a larger float and tube to measure. Because of the construction of the Kytola flowmeters, we can use the same size tube but put a different type float on the guide rod to measure a larger flow. You do need the same size tube but with a different scale.

Why quality matters when choosing a flowmeter?

Variable area flowmeters variety

Kytola has multiple different flowmeters for various needs

Kytola Instruments has been manufacturing and developing high quality flow measuring instruments and control devices since 1945. For the past 75 years, Kytola has been steadily grown to an internationally recognized enterprise that focuses in engineering and manufacturing products that are made to last.

What is Kytola’s recipe for its success?

The answer is actually very simple: customers want constant high quality, accuracy and reliability.

Kytola’s customer orientated and highly skilled staff is always ready to listen customers’ needs and eagerly responding to those while prioritizing long lasting, high quality solutions.

There are numerous producers of flow meters which manufacturing methods and standards are not as high as Kytola’s and consequently the accuracy and constant quality suffers from it. These flow meters might be a lot cheaper to produce but typically have many disadvantages.

If you would put such a flowmeter under a microscope, you would see that the inner tube where the float is moving up and down is very rough. A small bit of contamination or moist will stick to the wall causing the float not to move freely.


Kytola flowmeters are produced with state-of-the-art CNC machines which provide their impeccable quality compared to several products on the market. CNC machines are high precision tools that are computer controlled and make the manufacturing process highly efficient. Materials used for production go through a strict quality control system. The plastic gets a special treatment to prevent expansion or shrinking due to temperature and pressure changes while in use.

Choosing Kytola products has variety of benefits:

• Special scales
• Special ranges
• Even a combination of both scales and ranges
• Short delivery time.


While the production and manufacturing take place in Finland, Kytola has subsidiaries in North America, Sweden and Germany, as well as many local distributors all over the world, which means that choosing a Kytola flowmeter is just around the corner.

If you want to measure liquid or gas in a simple accurate way, Kytola Instruments is your answer.

When I am asked to tell the benefits of the Kytola oil lubrication system, I always start with a question: “Have you had a bearing failure within a year?” If the response is affirmative, I know that eventually the financial losses for the mill are inevitable for the following reasons:

• The machine must stop
• The bearing must be replaced
• In the worst case, a complete roller must be switched out
• Chance for fires are there due to extreme heat in the bearing house

There are many possibilities to lubricate your bearings but what is the key factor why customers choose Kytola products?

If the lubrication oil to the bearing is controlled, there is a much lower chance of a bearing failure.

There are many lubrication systems on the market, but Kytola Instruments products take a step further. Kytola products not only measure the oil flow going to the bearing, we also alarm it in 3 ways to make sure that if something goes wrong, you can take action while the machine is still running.

The Kytola oil lubrication system is based on positive displacement meters (oval gear meters) that measure a calibrated portion of the oil going to the bearing. If the meters slow down for a reason, the Kytola electronics will alarm it as a “low flow” signal. If the turning gears stop, it will alarm as a “low low flow” signal. By turning the bypass valve 90 degrees, you are redirecting the oil flow going to the bearing and you can investigate the meter while the lubrication is still at place. You can take off the cover, take out the gears and clean them.

There is also a “high flow” alarm. This alarm protects the bearing from not getting any oil while you think everything is OK.

Example: During a shutdown, maintenance is working on a bearing. Once finished they forget to hook up the lubrication point. Because there is no resistance from the bearing house, the flow will be much higher than normal, and the alarm will show.

Because the oval gear system from Kytola is so accurate, and the repeatability is fantastic, you can regulate the oil flow to the bearing at 0.1 pints/min. By cooling the bearing to the best temperature, the lifetime of the bearing will be much longer.

Kytola Instruments have many options for a single bearing systems to complete machines with several hundreds of bearings. Our skilled staff is ready to help and find the solution for your needs.
