This variable reluctance magnetic pickup coil (B170109) is designed to exceed the performance and application criteria of any standard or modified pickups. Its modular design allows it to be used with the B1750 positive displacement meter, and interface with all Blancett electronics. If using another manufacturer’s electronics with this meter, a Blancett B170210 pre-amplifier may be needed to correctly interface the devices.Output: 30 mV – 3 VAC Sine Wave (B170109) 0-10 V – Square Wave (B170210) 4-20 mA - 3 wire 4-20 mA output (B175420)Connector: 2-pin gold plated type to mate with MS3106-10SL-4S or equivalent (B170109) 3-pin gold plated type to mate with MS3106A-10SL-3S or equivalent (B170210) Temperature: -100 °F to +325 °F (-73 °C to +162 °C) (B170109) -20 °F to +160 °F (-29 °C to +71 °C) (B170210) 0 °F to +185 °F (-18 °C to + 85 °C) (B175420)Materials of Construction: 303/304 stainless steel shell and bottom, solid epoxy encapsulation, standard commercial finish

Operating Principle

K-factor

The Blancett Model B1750 positive displacement flow meter provides high measurement accuracy, trouble-free operation and long service life for fluids over a wide viscosity range. Applications include lubricants, fuels, chemicals and solvents, oils and greases. The B1750 meter is bi-directional (using appropriate electronics) and has an extremely large turndown ratio - up to 400:1 in some models - with full accuracy at extremely low flow rates.

Fluid entering the meter drives two gears. A non-intrusive sensor detects the movement of the gears and produces a sine wave pulse for each gear tooth that passes the path of the sensor face. The resulting pulse frequency is proportional to the actual flow rate, and it provides a highly accurate representation of the fluid flow. The meter is relatively insensitive to changes in viscosity and there is no need for straight run piping.

The K-factor represents the number of output pulses transmitted per unit volume of liquid passing through the positive displace-ment meter. Each meter has a unique K-factor that is determined during factory calibration. The K-factor is very constant and linear over the published flow range when liquid viscosity is greater than 100 cP. When liquid viscosity is less than 100 cP positive displacement meters can experience “fluid slip” in the measuring chamber due to migration of liquid around the internal moving parts. As a result, the linear (constant K-factor portion) measuring range of the flow meter is reduced. At viscosities less than 30 cP, positive displacement meters maintain published linearity over a 10:1 turndown range from the maximum published flow rate.

If using another manufacturer’s electronics with this meter, a Blancett B170210 pre-amplifier may be needed to correctly interface the devices.Output: 30 mV – 3 VAC Sine Wave (B170109) 0-10 V – Square Wave (B170210) 4-20 mA - 3 wire 4-20 mA output (B175420)Connector: 2-pin gold plated type to mate with MS3106-10SL-4S or equivalent (B170109) 3-pin gold plated type to mate with MS3106A-10SL-3S or equivalent (B170210) Temperature: -100 °F to +325 °F (-73 °C to +162 °C) (B170109) -20 °F to +160 °F (-29 °C to +71 °C) (B170210) 0 °F to +185 °F (-18 °C to + 85 °C) (B175420)Materials of Construction: 303/304 stainless steel shell and bottom, solid epoxy encapsulation, standard commercial finish
