Dahi Bondad Instrument Department with its personnel’s knowledge and modern technologies, as well as using specialized personnel, has been able to play an important role in supplying, developing and updating instrumentation equipments in many projects, especially in the fields of oil and gas and petrochemical companies. Due to the company’s precision regarding the choice of the best Western European manufacturers to achieve its goals (improving the quality of the country’s industry) in the field of instrumentation, Dahi Bondad Company is the exclusive representative of SPRIANO company(Italy) in Iran.
SPRIANO founded in 1923 began t’s activity with manufacturing pressure and temperature gauges. In 1936 SPRIANO has been the first company in Italy that could manufacture a pneumatic equipments that made a significant progress in the Rubber, Oil & Gas and Food Industries. In 1970 SPRIANO started manufacturing a complete line of Control Valves branded MEC-RELA, Providing effective and efficient solutions for industrial applications. During the 1980’s, SPRIANO completed its technological transfer from pneumatics to electronics by developing a complete line of innovative instruments, the 2-wire system and microprocessor-based transmitters. Today, SPRIANO, with its reliance and experience, has played a major role in the field of petroleum, gas, power plants, steel, marine, medicine and food in the field of instrumental systems (pneumatics and electronics) for nearly a century.


Transmitter In the recent decades, SPRIANO has been able to design and build intelligent transmitters for receiving and transmitting data, which is one of the most important parts of a control unit, using the latest technology and knowledge of the world. SPRIANO transmitters with high reliability and suitable for any conditions and the possibility of communication through the HART protocols or FIELDBUS and other technical features have been able to come across the world in various projects. Level Transmitter SPRIANO has various types of level transmitters such as DP, TORQUE TUBE, FLOAT, SUBMERSIBLE and radar type with all the material which is used in the projects (SS, Inconel, Hastelloy C, Monel, Superduplex, and Titanium). Pressure Transmitter Temperature Transmitter Gauge Level Gauge Pressure Gauge Temperature Gauge Flow gauge   Switch Level Switch Flow switch Pressure switch Temperature switch Measuring Elements: Orifice Pitot tube Venturi Tube Meter run Restriction orifice   Multiphase Flow Meter (MFU/MFPM) This device was designed and built with SPRIANO and the University of Rome cooperation, with the investment finance of ENI company. The machine will be able to measure the flow rate of oil, gas and water from the oil wells simultaneously without the usage of radioactive material.
