Product Description

Fuel flowmeters of Direct serie are used  for fuel consumption measurement in range between ****0 liters/hour.  Direct serie have many modifications, you can choose model at PRODUCT SPEC tab.


Note:
Most diesel engines have fuel supply system with fuel supply line and fuel return line. To know engine fuel consumption you need to measure both fuel flows with Delta flowmeter, or change fuel supply system for Direct flow meter application.


High-precision measurement
High corrosion resistance
Strong electronic circuit protection
Sealed automobile connector on sensor body
Indication lights provide easy understanding state of device
Fuel flow meters Direct are made from hard aluminium alloy, measuring chambers have antifriction coating, in both measuring chambers fuel temperature sensor is installed. Each manufactured flowmeter is pre-calibrated for differential application. Thereby Delta flow meters can provide accurate results in any mode of engine operation.

Unlike some other manufacturers, Direct flow meter warranty is not limited by passed flow. 3 year without flow limitations.


 

• Connecting thread    M*4x1, 5
• Max pressure    2.5 MPa
• Power voltage, V    *0 *0
• Reverse polarity protection    Yes
• Measuring accuracy    ±1%
• Temperature range,°C    **0 **5
• Maximum flow rate in l/h    **0
• Output interface    pulses, RS**2, RS**5, K-Line, CAN
• Seal rating    IP *6

Digit index means maximum fuel rate in each measuring chamber. It is a main parameter to choose suitable flow meter.

Simpliest version of flow meter has P index. Due to high quality of measuring chambers P-serie provide enough precision even without microcontroller circuit.

In Direct PH flow meters Hall-sensors are used instead of reed switch. That provide protection from external magnetic field.

PN fuel flow meter has powerful STM*2 processor inside. PN flowmeters have some advantages over P-serie:
1. Calibration table is not used for compromised coefficient calculation but recorded in non-volatile memory of flow meter. And calibration coefficients are applied in real-time. So, PN-flow meter always have same weight of pulse (normalized output).
Also precision of measurement is better (1% error instead of 2%).
2. Instead of reed switches Hall effect sensors are used.
3. Sensor can detect external intervention in operation and store this fact in memory
4. PN meter can provide not only fuel consumption but some other parameters : operation time of diesel, fuel consumption in different operation modes (idle, normal load, overload, external intervention) and time of operation in these modes. This information is available via RS**2/RS**5 interface   Direct PN(RS), or via K-line in Direct PN.
5. Temperature sensor and temperature compensation.
6. No need in check valve, because of smart processing of fuel vibration and software flow direction autodetection.
