Introduction
PFM 3000 has been designed for the servicing and hydraulic balancing of heating and cooling systems. It is equipped with a number of added built-in functions that make your work enjoyable.
The instrument is small. Its hard metal case lets you use it even under severe outdoor conditions. Even if you spill water on the case, PFM 3000 stays intact. A delivery includes standard RS232 interface and user software for the processing of gathered data.
A basic modulus of the instrument is a differential manometer with digital pressure processing. It is equipped with a built-in pressure sensor. The manometer combines the advantages of digital technology and compensates temperature dependence and the non-linear character of measuring. It makes possible the measuring of overpressure or underpressure in a system and the measuring of differential pressure. Using pressure difference at a balancing or measuring component you can measure flow at particular branches of a system and balance the heating system. Excellent features of the manometer enable further accurate measuring.
An external thermometer modulus is a part of the basic measuring equipment of the instrument. It enables to measure the temperature of a medium. The thermometer connects to the RS232 interface connector. One finds it easy to work with, as its dimensions are compatible with the dimensions of the measuring needles of balancing valves. The measuring spike of the thermometer should be plugged into an output for the measuring of differential flow. Along with other data temperature is being recorded in the
PFM 3000
instrument’s memory.
A built-in flow meter modulus is an indispensable instrument for the balancing of hydraulic systems. It calculates flow at a particular branch of a heating system out of pressure difference at a measuring element. The memory of the instrument keeps the characteristics of balancing and measuring elements of established producers. You can choose a particular type in the instrument’s menu.
There is an automatic flow correction function for flow measuring in systems with non-freezing additives or cooling systems.
A valve presetting calculation modulus is an revelsal part of the flow meter modulus. The output of the valve presetting calculation function is valve presetting for required flow. The function calculates valve presetting using valve characteristics stored in the memory. Therefore you always receive the right value of presetting.
An integrated recording modulus including a real time circuit is another positive feature of the instrument. The time circuit is all time powered from apparatus lithium battery.
The modulus helps keep records from project realisation or diagnose time actions in a heating system. The memory stores pressure, flow, temperature, chosen valve, valve presetting and measurement identification data, which helps you process and evaluate results on your PC. While recording measured data with a longer recording period, the instrument switches automatically to the sleep mode. This is enabled by a long-term recording function with energy coming from an internal source.
You can record data at different points of the heating system and have the current state of the system processed in your office. You can also choose a periodical recording. The

PFM 3000
analysis of time actions will help you choose an optimum system solution.
To download recorded data into your PC you can use software included in the delivery. The software makes it possible to display data in a chart or graph. They can also be printed. Data can be exported in standard PC formats and processed by a text editor, chart processor or database programs.
A heating system balancing modulus seems to be the most important component for the user. The modulus calculates the balancing of the system with many branches. It makes it possible to regulate even a complicated heating system including a common valve. A sophisticated calculation method optimises hydraulic ratios in the system and produces a project aiming at minimum energy loss in the system. The method reduces substantially the time needed for balancing. The function calculates valve presetting directly using the characteristics stored in the memory. Therefore you always receive the right presetting value.

Important User Notice
If you have previously used the instrument to measure liquid medium, do not expose it to temperature lower than the point of congelation of measured liquid. The pressure sensor may be damaged.
Inputs for measuring tubing are equipped with sintered filters - filtering capacity 50 m. When measuring in systems with a lot of dirt, filters get fouled. If the instrument's display indicates high pressure or one of pressure inputs does not work after measuring tubing have been disconnected, replace the filters.
Putting the Instrument into Operation
PFM 3000 is delivered with precharged lithiun battery and is ready to run immediately. Please check apparatus clock after first switch on.
Battery Charging
During measuring you can see battery state after hot key 
pushing. The battery capacity baragraph appears on display
6
Message Low Battery! flashes on the display every 15 sec bellow battery capacity 5%. You can work in this state about 6 hours, after it PFM 3000 automatically switches off.
Connect battery charger into conector under the cover at PFM 3000 bottom. Charging time is about 7 hours.
Deaeration of Connecting Tubes
To minimize measurement errors, deaerate the connecting tubing of the instrument. Take a quick coupler R20 off the tubing by pressing a safety ring (black collar) towards the quick coupler. Do not disconnect the quick coupler merely by pulling or force. The surface of the tubing or screw joint might be damaged. Connect the tubing to the measuring valve by a quick coupler R21 or to a discharge cock by means of a measuring adaptor. Flush out the tubing with water until air bubbles disappear. Put back the quick coupler R20.
PFM 3000 Zero Measuring Correction
When measuring zero pressure will take an error after a time of PFM 3000 using, you can correct this effect by ZERO function. In the instant that zero error is grater some kPa, we recommend clean or change sintered filters in apparatus
PFM 3000
hoses. While it has not requested effect, special maintenance is needed.
Zero is not stored in PFM 3000 configuration and not corrected value is measured after new switch on.
Functions of Keys on the Instrument's Keyboard
Keys with standard numbers or letters are used to enter data into computer. Following keys have special functions:
Switches the instrument on and off. To switch on the instrument, hold the key for one second.
Resets a reading about pressure on the display. The key also corrects possible zero instability and the dependence of the differential pressure on static pressure.
If in the measuring function, it opens the menu. It is used for the upward movement within the menu. If you press the key while entering data, the new value will not be saved. The previous data will be kept.
Serves to accept a value or a selected command in menu.
Hot key Valve. While in the measuring mode, it opens a selection of valves.
Hot key Preset. While in the measuring mode, it opens a valve presetting.
Hot key Battery. While in the measuring mode, it opens battery capacity display.
